Differential Diagnosis in Orthopaedic Oncology. When considering hyperparathyroidism, look for evidence of subperiosteal bone resorption. Finally other clues need to be considered, such as a lesion's localization within the skeleton and within the bone, any periosteal reaction, cortical destruction, matrix calcifications, etc. (2007) ISBN:0781765188. AJR 2000; 175:261-263. Usually one bone is involved. Radiographs are specific but suffer from low sensitivity 1. 6. Imaging is often helpful in determining a diagnosis, and it can sometimes make a particular diagnosis nearly certain. 11. Osteoblastic metastatic disease (see Table 33.1): More often multiple with increased uptake on bone scan. There are calcified strands within the soft tissues. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. Notice that the cortical bone extends into the lesion. UW Radiology Sclerotic Lesions of Bone <-Lucent Lesions of Bone | Periosteal Reaction-> What does it mean that a lesion is sclerotic? Surrounded by a prominent zone of reactive sclerosis due to a periosteal and endosteal reaction, which may obscure the central nidus. Not infrequently encountered as coincidental finding at later age. Case Report Med. Here an incidental finding of several eccentric sclerotic lesions of the distal femur. We provide care in several areas of orthopedics, such as: hand and wrist care, foot and ankle care, and joint replacement. A disadvantage of MRI is that the detection is poor in bones with a small marrow cavity such as the ribs and these bones are better investigated with CT 2,3. Bone islands demonstrate uniformly low Centrally there is an ill-defined osteolytic area. Metastases and multiple myelomaIn patients > 40 years metastases and multiple myeloma are the most common bone tumors.Metastases under the age of 40 are extremely rare, unless a patient is known to have a primary malignancy.Metastases could be included in the differential diagnosis if a younger patient is known to have a malignancy, such as neuroblastoma, rhabdomyosarcoma or retinoblastoma. Clin Orthop Relat Res. Lippincott Williams & Wilkins. The use of radiological imaging in medical care dates back to 1895 when It is nost commonly located on the posterior side of the distal meta-diaphysis of the femur. The most common focal metastatic lesions originate from the breast (37%), lung (15%), kidney (6%), and thyroid (4%) 43. Small osteolytic lesion (up to 1.5 cm) with or without central calcification. Magnetic resonance imaging of subchondral bone marrow lesions in association with osteoarthritis. Differentiating between a diaphyseal and a metaphyseal location is not always possible. Here, we showed that sBT values are higher in patients presenting 496 with bone loss . This part corresponds to a zone of high SI on T2-WI with FS on the right. Fibrous dysplasia, Enchondroma, NOF and SBC are common bone lesions.They will not present with a periosteal reaction unless there is a fracture.If no fracture is present, these bone tumors can be excluded. Central location most common with some expansion and cortical thinning. 2 ed. Growth of osteochondroma in skeletally mature patient, Irregular or indistinct surface of lesions, focal lucent regions in interior of lesions, presence of soft tissue mass with scattered or irregular calcifications. However, a specific density range has not been specified for those terms 1. There are two kinds of mineralization: Chondroid matrix The image on the right is of a different patient who has an old NOF that shows complete fill in. If the process is slower growing, then the bone may have time to mount an offense and try to form a sclerotic area around the offender. Tumor Pathology- Bone Lesion Bone Tumor Osteomyelitis When you identify a bone lesion, follow this basic checklist to help you accurately describe the lesion and narrow your differential diagnosis: Bone Tumors and Tumorlike Conditions: Analysis with Conventional Radiography Theodore T. Miller Radiology 2008 246:3, 662-674 Hereditary sclerosing bone dysplasias result from some disturbance in the pathways involved in osteoblast or osteoclast regulation, leading to abnormal accumulation of bone. Symptoms include pain, abnormal sensations, loss of motor skills or coordination, or the loss of certain bodily functions. If the patient had fever and a proper clinical setting, osteomyelitis would be in the differential diagnosis. SWI:low signal intensity on the inverted magnitude and phase images 9. Mixed lytic and sclerotic bone metastases are characterized by the presence of both components, that is areas of bone destruction and areas of increased bone formation within one metastatic tumor deposit or one primary tumor that features both kinds of bone metastases, namely osteolytic and osteoblastic metastases 1. 4. {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. Causes: corticosteroid use, sickle cell disease, trauma, Gaucher's disease, renal transplantation. Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. ADVERTISEMENT: Supporters see fewer/no ads. Many sclerotic lesions in patients > 20 years are healed, previously osteolytic lesions which have ossified, such as: NOF, EG, SBC, ABC and chondroblastoma. There are two patterns of periosteal reaction: a benign and an aggressive type. Prevalence of 3-5% in patients with hereditary multiple osteohondromas. The bone marrow compartment is not involved which is important for the surgical strategy. In most cases of osteoid osteoma the radiographic appearance is determined by the reactive sclerosis. A molecular classification has been also proposed. Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. Based on the morphology and the age of the patients, these lesions are benign. Scuba Certification; Private Scuba Lessons; Scuba Refresher for Certified Divers; Try Scuba Diving; Enriched Air Diver (Nitrox) Osteosarcoma (2) Multiple enchondromas are seen in Morbus Ollier. Wide zone of transition CT can detect osteoblastic metastases with a higher sensitivity than plain radiographs and shines in the assessment of bones which are characterized by a small bone marrow cavity and a high amount of cortical bone such as the ribs 2,3. some benign entities in this region may mimic malignancy if analyzed using classical bone-tumor criteria, and proper patient management requires being familiar with these presentations. The NK cell type is seen as a sheet of soft tissue in the nasal cavity with bone destruction and erosion without any sclerosis. It is a feature of malignant bone tumors. Symptoms are usually absent, however, in adult patients with a chondroid lesion in a long bone, particularly of larger size, always consider low-grade chondrosarcoma. This proved to be a reactive calcification secondary to trauma. . Purpose: To determine if sclerotic bone lesions evident at body computed tomography (CT) are of value as a diagnostic criterion of tuberous sclerosis complex (TSC) and in the differentiation of TSC with lymphangioleiomyomatosis (LAM) from sporadic LAM. A benign type of periosteal reaction is a thick, wavy and uniform callus formation resulting from chronic irritation. However, a specific density range has not been specified for those terms 1. In the cases in which the solitary sclerotic lesion has increased, uptake on bone scan, follow-up CT, or plain film imaging is recommended at 3-, 6-, and 12-month intervals. Common: Metastases, multiple myeloma, multiple enchondromas. Ali Mohammed Hammamy R, Farooqui K, Ghadban W. Sclerotic Bone Metastasis in Pulmonary Adenocarcinoma. Notice the numerous ill-defined osteoblastic metastases. 2017;11(1):321. 2020;60(Suppl 1):1-16. (B) In another patient, a 21-year-old woman, note a radiolucent lesion with sclerotic border affecting the medial cortex of the distal femur ( arrows ). Adam Greenspan, Gernot Jundt, Wolfgang Remagen. Typically a NOF presents as an eccentric well-defined lytic lesion, usually found as a coincidental finding. In this paper, we review the recent years of literature on deep learning-based multiple-lesion recognition. T2-weighted MR image reveals a lobulated mass with high signal intensity. Ossification in parosteal osteosaroma is usually more mature in the center than at the periphery. 2021;13(22):5711. In this case we see the pathognomonic triad of bone expansion, cortical thickening and trabecular bone thickening in the mixed lytic and sclerotic phase of Paget's disease of right hemipelvis. About Us; Staff; Camps; Scuba. There are a number of other helpful findings you can look for that can help you to cone in on or away from specific entities in one of these differential lists. AJR Am J Roentgenol. It is associated with near total fat loss, severe insulin resistance and hypoleptinemia leading to metabolic derangements.Case PresentationWe report a 25- year- old female with 1-Acylglycerol-3-phosphate-O-acyltransferase 2 (APGAT2) mutation, and both sclerotic and lytic bone lesions together for the first time. Parkinson's disease, multiple sclerosis, brain tumors and brain trauma [2]. Abbreviations used: The most important determinators in the analysis of a potential bone tumor are: It is important to realize that the plain radiograph is the most useful examination for differentiating these lesions.CT and MRI are only helpful in selected cases. Sclerosis is usually the most prominent finding in subacute and chronic osteomyelitis. The differential diagnosis mostly depends on the age of the patient and the findings on the conventional radiographs. Impact of Sclerotic. Here a patient with a mineralized mass in the soft tissues. Well, generally, it means that it is due to a fairly slow-growing process. There are no calcifications.

In the article Bone Tumors - Differential diagnosis we discussed a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. Guidelines for the Diagnostic Management of Incidental Solitary Bone Lesions on CT and MRI in Adults: Bone Reporting and Data System (Bone-RADS). Spinal lesions are commonly spotted on imaging tests. 4. Differential Diagnosis of Diffuse Sclerotic Bone Lesions. Skeletal Radiol. The image shows a calcified lesion in the proximal tibia without suspicious features. In the table the most common sclerotic bone tumors and tumor-like lesions in different age-groups are presented. The differential diagnosis of bone lesions that result in bony sclerosis will be given. PET features high sensitivity in the detection of bone metastases especially 18 NaF-PET is suitable for the detection of sclerotic metastases since it shows tracer uptake in locations with osteoblastic activity and is more accurate than FDG-PET 3. Benign lesion consisting of well-differentiated mature bone tissue within the medullary cavity. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-8429. Malignant transformation Radiographic or CT features that suggest malignancy: Use MRI with water-sensitive sequence (T2 FS) to determine cartilage cap thickness. 7. Bone scintigraphy can be either negative or show limited uptake. Continue with the MR-images. It classically presents with nocturnal pain in young patients, painful scoliosis, and marked relief from NSAIDs (nonsteroidal anti-inflammatory drugs). The differential diagnosis of bone lesions that result in bony sclerosis will be given. {"url":"/signup-modal-props.json?lang=us"}, Gaillard F, Knipe H, Weerakkody Y, et al. mutation, and both sclerotic and lytic bone lesions together for the first time. Calcifications in chondroid tumors have many descriptions: rings-and-arcs, popcorn, focal stippled or flocculent. MRI features high sensitivity and high specificity for the demonstration of bone metastases in general and for assessing the bone marrow 2,3. AJR 1995;164:573-580, Online teaching by the Musculoskeletal Radiology academic section of the University of Washington, by Theodore Miller March 2008 Radiology, 246, 662-674, by Nancy M. Major, Clyde A. Helms and William J. Richardson. NOF, fibrous dysplasia, multifocal osteomyelitis, enchondromas, osteochondoma, leukemia and metastatic Ewing' s sarcoma. The bone scan is also helpful to look for additional sites of increased uptake that may not have been imaged, such as multiple nontraumatic rib, calvarial, or long bone lesions, which would strongly suggest the diagnosis of metastatic disease. See article: bone metastases. Osteoma consists of densely compact bone. Amorphous mineralisation is present in most lesions. The evaluation of a solitary bony lesion in the spine may be more challenging and will often require additional diagnostic testing if benign imaging features are not present on MRI. The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. Here a well-defined mixed sclerotic-lytic lesion of the left iliac bone. A cold bone scan is helpful in distinguishing the bone island from a sclerotic metastasis, whereas a warm bone scan is nondiagnostic. Osteoid osteoma (2) The homogeneous enhancement in the upper part with edema and cortical thickening are not typical for a low-grade chondrosarcoma. Here images of a patient with breast cancer. Azar A, Garner H, Rhodes N, Yarlagadda B, Wessell D. CT Attenuation Values Do Not Reliably Distinguish Benign Sclerotic Lesions From Osteoblastic Metastases in Patients Undergoing Bone Biopsy. Metastatic sclerotic bone lesions present in three typical patterns, focal, variegated, or diffuse based on the histological origin of the primary tumor. Typical presentation: central lesion in metaphysis or diaphysis with a well defined serpentiginous border. Lesions in the bone are usually identified on radiographic images - chiefly X-rays - but also on CT and MRI scans. Notice that many benign osteolytic lesions that are frequently seen in younger age groups may heal and appear as sclerotic lesions in the middle aged group. It is barely visible within the bone, but an agressive periostitis is seen (arrow). Development in centrally located osteochondromas like the pelvis, hip and shoulder is most common.

Sclerotic bone metastasis as initial manifestation of lung adenocarcinoma in a patient with SLE - The Lancet Oncology Clinical Picture | Volume 24, ISSUE 3, e144, March 2023 Sclerotic bone metastasis as initial manifestation of lung adenocarcinoma in a patient with SLE Prof Ruchi Mittal, MD Debashis Maikap, MD Pallavi Mishra, MD SusanaBoronat, IgnasiBarber, VivekPargaonkar, JoshuaChang, Elizabeth A.Thiele . Results: In 24 patients, 52 new sclerotic lesions observed during therapy were selected for re-evaluation of conventional radiographs and bone scans. Enchondroma, the most commonly encountered lesion of the phalanges. If there are multiple or polyostotic lesions, the differential diagnosis must be adjusted. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. (2005) ISBN: 9780721602707 -. Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Authors CT scan is usually very helpful in detecting the nidus and differentiating osteoid osteoma from other sclerotic lesions like osteoblastoma, osteomyelitis, arthritis, stress fracture and enostosis. Confavreux C, Follet H, Mitton D, Pialat J, Clzardin P. Fracture Risk Evaluation of Bone Metastases: A Burning Issue. 5. This is consistent with the diagnosis of a reactive process like myositis ossificans. Growth has been demonstrated well after skeletal maturity. MRI also may detect the nidus, combined with abundant bone marrow and soft tissue edema. Here an example of a patient with a stress fracture of the distal fibula. 105-118. Concerning the above factors the differential diagnosis includes the following lesions 1-3: sclerotic bone metastasis: might be solitary because no others are present or have been imaged, infection: e.g. Solitary sclerotic bone (osteosclerotic or osteoblastic) lesions are lesions of bone characterized by a higher density or attenuation on radiographs or computer tomography compared to the adjacent trabecular bone. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. Most cases of chronic osteomyelitis look pretty nonspecific. 1. Patients with sclerotic lesions due to metastasis often have a history of prior malignant disease. Starting on day 28, sclerotic changes surrounding the bone absorption area were detected. Sclerotic bone lesions are commonly detected by abdominal MRI in children with tuberous sclerosis complex. Here some typical examples of bone tumors in the spine. 5. 3. Large lesions tend to expand into both areas. Uncommonly it can be difficult to differentiate a stress fracture from a pathologic fracture, that occurs at the site of a bone tumor. Biopsy revealed dedifferentiated chondrosarcoma. Systematic Approach of Sclerotic Bone Lesions Basis on Imaging Findings. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Clinically relevant bone metastases are a major cause of morbidity and mortality for prostate cancer patients. Breast cancer (usually mixed lytic/sclerotic), Bone islands do not have edema in the adjacent bone marrow or extension into surrounding soft tissue or adjacent bony destruction. The lesion is predominantly calcified. colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement. At the periphery of the infarct a zone of relative high signal intensity on T2WI may be found. Peripheral chondrosarcoma, arising from an osteochondroma (exostosis). The differential diagnosis of solitary sclerotic bone lesions can be narrowed down according to the following factors 1-3: cartilaginous matrix (rings and arcs appearance). D'Oronzo S, Coleman R, Brown J, Silvestris F. Metastatic Bone Disease: Pathogenesis and Therapeutic Options. Check for errors and try again. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. Sclerotic bone metastases can arise from several different primary malignancies including 1-3: mucinous adenocarcinoma of the gastrointestinal tract (e.g. by Mulder JD, et al. Bone scan shows no high activity, opposed to low-grade intraosseous osteosarcoma. Sclerotic osteoblastic metastases must be included in the differential diagnosis of any sclerotic bone lesion in a patient > 40 years. RT @JMGardnerMD: 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Usually it is a lesion of childhood or young adults. Generic Differential Diagnosis of Sclerotic Bone Lesions. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. Secondary bone cancer is much more common than primary bone . However, these lesions are often underreported, mainly because the subject is not well known to general radiologists who struggle with the imaging approach and disease entities. 3, Increased uptake on bone scan associated with a solitary sclerotic lesion is atypical and therefore more worrisome, but largely unhelpful as there are many reports of bone islands having increased Tc-99 m hydroxydiphosphonate (HDP) uptake. The mnemonic I VINDICATE is a commonly used mnemonic for the differential diagnostis of any radiological lesion. Chordoma is usually seen in the spine and base of the skull. 2003;415(415 Suppl):S4-13. Notice that the mineralization is predominantly in the periphery of the mass and that there is a lucent zone between the mass and the cortical bone. Differentiating a bone infarct from an enchondroma or low-grade chondrosarcoma on plain films can be difficult or even impossible. A high grade chondrosarcoma must be considered in the differential diagnosis. This 'neocortex' can be smooth and uninterrupted, but may also be focally interrupted in more aggressive lesions like GCT. Here two other lesions in different patients that proved to be chondrosarcoma. Subchondral bone attrition is the flattening or depression of the bone surface that forms part of a joint. AJR Am J Roentgenol. Several genes have been discovered that, when disrupted, result in specific types . Amsterdam: Elsevier, 1993. The juxtacortical mass has a high SI and lobulated contours. In aggressive periostitis the periosteum does not have time to consolidate. This benign reactive process is most commonly found adjacent to the cortex of phalanges of hands or feet (75%). Usually stress fractures are easy to recognize. Most commonly originate from prostate and breast cancer and less frequently from lung cancer, lymphoma or carcinoid. Eosinophilic Granuloma and infections should be mentioned in the differential diagnosis of almost any bone lesion in patients < 20 years. Disappearane of calcifications in a pre-existing enchondroma should raise the suspicion of malignant transformation. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. 1. 2018;2018:1-5. Infection may be well-defined or ill-defined osteolytic, and even sclerotic. Some prefer to divide patients into two age groups: 30 years. Less common: Fibrous dysplasia, Brown tumors of hyperparathyroidism, bone infarcts. 2018;10(6):156. A juxtacortical chondrosarcoma has be considered in the differential diagnosis when a mineralized lesion adjacent to the cortical bone is seen. Non-ossifying fibroma (NOF) can be encoutered occasionally as a partial or completely sclerotic lesion. Here images of a patient with prostate cancer. When considering congenital causes of sclerotic lesions, benign causes such as bone islands or osteopoikilosis usually have a fairly typical appearance and are hard to mistake. In patients In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered On the left three bone lesions with a narrow zone of transition. Gulati V, Chalian M, Yi J, Thakur U, Chhabra A. Sclerotic Bone Lesions Caused by Non-Infectious and Non-Neoplastic Diseases: A Review of the Imaging and Clinicopathologic Findings. Macedo F, Ladeira K, Pinho F et al. The contour of the involved bone is usually normal or with mild expansive remodelling. Intense uptake on bone scintigraphy as we would expect in high grade chondrosarcoma. AJR 2005; 185:915-924. Distinction of Long Bone Stress Fractures from Pathologic Fractures on Cross-Sectional Imaging: How Successful Are We? Signed by [redacted] on 1/17/2020 11:42 AM Narrative These are inert filled-in non-ossifying fibromas. These are infections and eosinophilic granuloma. Density measurements on CT scan revealed greater than 1,000 HU throughout the lesion. Click here for more detailed information about NOF. Unable to process the form. Presentation: pain, mass, pathologic fracture. J Korean Soc Radiol. Despite their remarkable clinical success, the low degradation rate of these materials hampers a broader clinical use. Mnemonic for multiple oseolytic lesions: FEEMHI: It is assumed that several tumor-derived growth factors increase osteoblast activity while osteoclast activity is restricted 3,4. Brant WE, Helms CA. The radiological report should include a description of the following 2: location and size including the whole extent of disease load, pain attributable to the lesion (if known), Treatment of bone metastases, in general, is usually planned by a multidisciplinary team 10. 5, In the cases with no known primary malignancy that are being followed with serial imaging, if the lesion increases in diameter by greater than 25% at 6 months or less, or greater than 50% at 12 months, open biopsy has been recommended by Brien et al. Coronal MR image demonstrates subtle low intensity line representing the fracture. Sclerotic Lesions of the Spine 1311. predominant hypointensity on all imaging sequences mimicking a sclerotic process due to a variety of fac- . 3. Age is the most important clinical clue in differentiating possible bone tumors.There are many ways of splitting age groups, as can be seen in the table, where the morphology of a bone lesion is combined with the age of the patient. This solitary, uniformly high-density lesion with neither edema in the surrounding bone marrow nor extension into the surrounding soft tissue most likely represents a giant bone island. Radionuclide bone scan shows a classic "double density" sign of osteoid osteoma located in the tibia: markedly increased radioactivity in the center ( arrow) is related to the nidus, less active areas ( arrowheads) represent reactive sclerosis. Logistic regression analyses were used to assess the association of joint form and lesions on imaging for axSpA patients and controls. Non-ossifying fibroma which has been filled in. Here on a radiograph the typical calcifications in the chondroid matrix of an enchondroma. If the disorder it is reacting to is rapidly progressive, there may only be time for retreat (defense). Bone metastases start with the tropism of cancer cells to the bone through different multi-step tumor-host interactions, as described by the . Radiographs are specific but suffer from low sensitivity 1. Mark Blumenkehl, MD is a specialist in Gastroenterology whose practice locations include: Detroit, Sterling Hgts Enchondroma is a fairly common benign cartilaginaous lesion which may present as an entirely lytic lesion without any calcification, as a dense calcified lesion or as a mixed leson with osteolysis and calcifications. The illustration on the left shows the preferred locations of the most common bone tumors. Differential diagnosis As part of the test, a healthcare professional takes a sample of the CSF 1991;167(9):549-52. Most common malignant bone tumor, which is almost always low-grade, Primary sites of origin: proximal long bones, around knee, pelvis and shoulder girdle, usually central and metaphyseal. A mean CT attenuation threshold of 885 HU and a maximum attenuation threshold of 1060 HU has been found supportive in the differentiation of untreated osteoblastic and bone island in one study 7, but the exclusive use of attenuation values for the assessment of sclerotic bone lesions has been discouraged 8. However, if one sees sinus tracts associated with a sclerotic area, one should strongly consider osteomyelitis. {"url":"/signup-modal-props.json?lang=us"}, Niknejad M, Bell D, Tatco V, et al. In the case of benign, slowly growing lesions, the periosteum has time to lay down thick new bone and remodel it into a more normal-appearing cortex. A mnemonicfor remembering the causes of diffuse bony sclerosis is: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Both of these entities may have an aggressive growth pattern. Park S, Lee I, Cho K et al. sclerosing osteomyelitis of Garr, aggressive features might require an oncological referral and/or biopsy 1, history of malignancy will almost always require additional imaging, follow-up or oncologic referral, high CT attenuation values might help in the differentiation of bone island from osteoblastic metastases 5 but attenuation values should not be used exclusively for the assessment of sclerotic bone lesions 6, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Sclerosing bone dysplasias are skeletal abnormalities of varying severity with a wide range of radiologic, clinical, and genetic features. A sclerotic lesion is an unusual hardening or thickening of your bone. Check for errors and try again. It can identify small or large tumors, multiple sclerosis (MS), encephalitis (brain inflammation), or meningitis (inflammation of the meninges that lie between the brain and the skull). Typically presents as a lytic lesion in a flat bone, vertebra or diaphysis of long bone. Bone Metastases: An Overview. You may have been surprised to see metastatic disease listed as a leading cause for diffuse sclerotic bones. In general, they're slow-growing.. 4 , 5 , 6. Polyostotic lesions Bone islands can be large at presentation. In breast cancer, metastases may present as lytic lesions that may become sclerotic expressing a favourable response to chemotherapy. Solitary sclerotic bone (osteosclerotic or osteoblastic) lesions are lesions of bone characterized by a higher density or attenuation on radiographs or computer tomography compared to the adjacent trabecular bone. .
