J Korean Soc Radiol. 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. Lumbar CT-HU has the highest pooled correlation (r 2 =0.6) with both spine DEXA and lowest skeletal t-score followed by lumbar CT-HU with hip DEXA (r 2 =0.5) and lumbar MRI with hip (r 2 =0.44) and spine (r 2 =0.41) DEXA. Small osteolytic lesion (up to 1.5 cm) with or without central calcification. Osteoblastic metastases (2) Adamantinoma in case of a sclerotic lesion with several lucencies of the tibia in a young patient. The most common appearance is the mixed lytic-sclerotic. Radiographs are specific but suffer from low sensitivity 1. mutation, and both sclerotic and lytic bone lesions together for the first time. Check for errors and try again. Notice the numerous ill-defined osteoblastic metastases. . Click here for more examples of chondroblastoma. Society of Skeletal Radiology- White Paper. 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. DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. Spinal lesions are commonly spotted on imaging tests. In fact, in areas where sickle cell disease is common, this may be the leading cause of diffuse sclerotic bones. A periosteal reaction is a non-specific reaction and will occur whenever the periosteum is irritated by a malignant tumor, benign tumor, infection or trauma. (2007) ISBN:0781765188. Click here for more detailed information about fibrous dysplasia. Imaging is often helpful in determining a diagnosis, and it can sometimes make a particular diagnosis nearly certain. Check for errors and try again. DD: old SBC. On the right T2-WI with FS of same patient.. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. Differentiation of Predominantly Osteoblastic and Osteolytic Spine Metastases by Using Susceptibility-Weighted MRI. In breast cancer, metastases may present as lytic lesions that may become sclerotic expressing a favourable response to chemotherapy. Sclerotic Lesions of the Spine 1311. predominant hypointensity on all imaging sequences mimicking a sclerotic process due to a variety of fac- . Impact of Sclerotic. Skeletal Radiol. It is a feature of malignant bone tumors. Osteoma consists of densely compact bone. Bone metastases start with the tropism of cancer cells to the bone through different multi-step tumor-host interactions, as described by the . The cortical bone and bone marrow compartment are not involved. 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. Geode or subchondral cyst in the navicular bone, Geode or subchondral cyst in the tarsal bone, X-ray and MRI of a chondroblasoma in the tarsal bone, Chondromyxoid fibroma (CMF) in the calcaneus. Here an illustration of the most common sclerotic bone tumors. A chondrosarcoma was diagnosed at biopsy. Radiological atlas of bone tumours of the Netherlands Committee on 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. CT-HU has stronger correlations with DEXA than MRI measurements. Ulano A, Bredella M, Burke P et al. Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. Resonance Imaging Saeed M. Bafaraj . Top five location of bone tumors in alphabethic order: Aneurysmal Bone Cyst -tibia, femur, fibula, spine, humerusAdamantinoma -tibia shaft, mandibleChondroblastoma -femur, humerus, tibia, tarsal bone (calc), patellaChondromyxoid fibroma - tibia, femur, tarsal bone, phalanx foot, fibulaChondrosarcoma - femur, rib, iliac bone, humerus, tibiaChordoma -sacrococcygeal, spheno-occipital, cervical, lumbar, thoracicEosinophilic Granuloma -femur, skull, iliac bone, rib, vertebraEnchondroma -phalanges of hands and feet, femur, humerus, metacarpals, ribEwing's sarcoma - femur, iliac bone, fibula, rib, tibiaFibrous dysplasia - femur, tibia, rib, skull, humerusGiant Cell Tumor - femur, tibia, fibula, humerus, distal radiusHemangioma - spine, ribs, craniofacial bones, femur, tibiaLymphoma - femur, tibia, humerus, iliac bone, vertebraMetastases - vertebrae, ribs, pelvis, femur, humerusNon Ossifying Fibroma - tibia, femur, fibula, humerusOsteoid osteoma - femur, tibia, spine, tarsal bone, phalanxOsteoblastoma - spine, tarsal bone (calc), femur, tibia, humerusOsteochondroma - femur, humerus, tibia, fibula, pelvisOsteomyelitis - femur, tibia, humerus, fibula, radiusOsteosarcoma -femur, tibia, humerus, fibula, iliac boneSolitary Bone Cyst -proximal humerus, proximal femur, calcaneal bone, iliac bone. Plain films typically reveal lesions with moth-eaten or permeative pattern of the transition zone with irregular cortical destruction and an interrupted periosteal reaction with soft tissue extension. Typically a NOF presents as an eccentric well-defined lytic lesion, usually found as a coincidental finding. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-8429. Regarding bone disease in SM, increased sBT levels have been 493 associated with both bone sclerosis (due to unknown mechanisms) (8, 18, 19) and 494 osteoporosis (it has been hypothesized that tryptase could induce the production of 495 OPG (61)) (4, 17). Mnemonic for multiple oseolytic lesions: FEEMHI: Biopsy revealed dedifferentiated chondrosarcoma. On the left three bone lesions with a narrow zone of transition. A periosteal chondroma may have the same imaging characteristics, however, these are almost always much smaller. Systematic Approach of Sclerotic Bone Lesions Basis on Imaging Findings. A lucent, well-circumscribed lesion is seen with a surrounding thin sclerotic cortical rim on plain radiographs [ Figure 4 ]. Imaging: Most of the time, sclerotic lesions are benign. In patients Lippincott Williams & Wilkins. Here some typical examples of bone tumors in the spine. It is barely visible within the bone, but an agressive periostitis is seen (arrow). Rapid growth of the mineralized mass is not uncommon. However, a specific density range has not been specified for those terms 1. 9. AJR Am J Roentgenol. Increased uptake on bone scan has been reported in bone islands, especially giant ones, but warrants imaging follow-up. Studies suggest that beyond joint wear and tear . 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). The most common focal metastatic lesions originate from the breast (37%), lung (15%), kidney (6%), and thyroid (4%) 43. They usually affect posterior vertebral elements and their number and size increase with age. For the unexpected bone lesions, the distinguishing anatomic features and a generalized imaging approach will be reviewed for four frequently encountered scenarios: chondroid lesions, sclerotic bone lesions, osteolytic lesions, and areas of focal marrow abnormality. 2018;2018:1-5. Other benign lesions, like solitary bone cyst, fibrous dysplasia, chondroblastoma and other benign bone tumors may become inert and may also become sclerotic. (white arrows). giant cell tumor, metastasis, and myeloma; (3) sclerotic . Usually typical malignant features including permeative-motheaten pattern of destruction, irregular cortical destruction and aggressive (interrupted) periosteal reaction. Etiology CT imaging example of the location pattern of sclerotic bone lesions in the skull, spine, and pelvis of TSC patients and control subjects. All images were evaluated for joint form, erosion, sclerosis, fat metaplasia and bone marrow oedema (BMO) by two independent readers. Click here for more examples of enchondromas. There are calcified strands within the soft tissues. The X-ray features were divided into two groups according to typical and atypical skeletal lesions. Therefore, knowing the homogeneously sclerotic bone lesions can be useful, such as enostosis (bone island) (), osteoma (), and callus or bone graft.The plain radiography and CT images of enostosis consist of a circular or oblong area of dense bone with an irregular and speculated margin, which have been . Sclerotic bone lesions appear exclusively in middle aged black patients. Contact Information and Hours. A bone island larger than 1 cm is referred to as a giant bone island (12). AJR 2005; 185:915-924. In the table the most common sclerotic bone tumors and tumor-like lesions in different age-groups are presented. Coronal T1W image shows lobulated margins and peripheral low SI due to the calcifications. 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. Infections and eosinophilic granulomaInfections and eosinophilic granuloma are exceptional because they are benign lesions which can mimick a malignant bone tumor due to their aggressive biologic behavior. Once we have decided whether a bone lesion is sclerotic or osteolytic and whether it has a well-defined or ill-defined margins, the next question should be: how old is the patient? 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 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). Sclerotic jaw lesions are not rare and are frequently encountered on radiographs and computed tomography (CT). by Mulder JD et al Hall F & Gore S. Osteosclerotic Myeloma Variants. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-10490, {"containerId":"expandableQuestionsContainer","displayRelatedArticles":true,"displayNextQuestion":true,"displaySkipQuestion":true,"articleId":10490,"questionManager":null,"mcqUrl":"https://radiopaedia.org/articles/sclerotic-bone-metastases/questions/1747?lang=us"}. {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. These lesions were possibly misinterpreted as new when applying WHO criteria. A lumbar puncture (LP) is a diagnostic procedure used to obtain a sample of cerebrospinal fluid (CSF) to look for signs of infection or inflammation. In Section 2, we give the general technical route for classification, detection and segmentation of multiple-lesion.After that, in Section 3, the paper will review the recognition of multiple-lesion in six organ and tissue areas, including brain, eye, skin, breast, lung, and abdomen. Bone cyst is one of the manifestations of CGL with AGPAT2 mutation. Wide zone of transition Consider progression of osteohondroma to chondrosarcoma when cartilage cap measures > 10 mm. 5. An ill-defined border with a broad zone of transition is a sign of aggressive growth (1). Sclerotic bone lesions at abdominal magnetic resonance imaging in children with tuberous sclerosis complex. Ahuja S & Ernst H. Osteoblastic Bone Metastases in Medullary Thyroid Carcinoma. The lesion is predominantly calcified. 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. Chang C, Garner H, Ahlawat S et al. 6. Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. Usually new bone is added to one side of the cortex only. Sclerotic metastases arise from . Rib lesions detected on bone scintigraphy often require further characterization with radiography or CT to improve specificity (Figs. Magnetic resonance imaging of subchondral bone marrow lesions in association with osteoarthritis. Here a partially calcified mass against the proximal humerus with involvement of the cortical bone on an axial CT image. Bone cements such as polymethyl methacrylate and calcium phosphates have been widely used for the reconstruction of bone. Infection is seen in all ages. 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. Case 2: sclerotic metastases from prostate cancer, Generalised increased bone density (mnemonic). Diffuse bony sclerosis (mnemonic). Journal of Bone Oncology. Bone flare phenomenon was well described on bone scans; a study 25 revealed the appearance of new or worsening bone sclerosis at 3-month CT assessment in three of 67 castration-resistant prostate cancer (CRPC) patients undergoing systemic treatment. by Clyde A. Helms Differential Diagnosis in Orthopaedic Oncology. FD is often purely lytic, but may have a groundglass appearance as the matrix calcifies. Location within the skeleton General Considerations At the 1-year follow-up, the lesion was completely stable and no additional follow-up was recommended in the absence of symptoms. The diagnosis was fibrous dysplasia. Here a radiograph of the pelvis with a barely visible osteoblastic metastasis in the left iliac bone (blue arrow). Incidentally discovered, benign lesions also called enostoses, which are islands of cortical bone located in the cancellous bone. 33.1a) and sagittal short tau inversion recovery (STIR; Fig. Osteopetrosis and pyknodysostosis are likewise hard to mistake for other entities since the bones are denser than in any other disorder, and the long bones tend to have very tiny medullary canals. Sarcoidosis is a multi-system disease with a range of . The differential for multifocal lesions happens to be identical to that for focal lesions. World J Radiol. It could be blood or fluids released from fibrosis (scarred tissue) or necrosis (tissue death). In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered 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. Notice the lytic peripheral part with subtle calcifications. A sclerotic border especially indicates poor biological activity. Park S, Lee I, Cho K et al. Diffuse bony sclerosis (mnemonic) Last revised by Joshua Yap on 28 Jun 2022 Edit article Citation, DOI & article data A mnemonic for remembering the causes of diffuse bony sclerosis is: 3 M's PROOF Mnemonic 3 M's PROOF M: malignancy metastases ( osteoblastic metastases) lymphoma leukemia M: myelofibrosis M: mastocytosis S: sickle cell disease Sclerotic osteoblastic metastases must be included in the differential diagnosis of any sclerotic bone lesion in a patient > 40 years. 2010;35(22):E1221-9. Here an incidental finding of several eccentric sclerotic lesions of the distal femur. 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. Confavreux C, Follet H, Mitton D, Pialat J, Clzardin P. Fracture Risk Evaluation of Bone Metastases: A Burning Issue. This feature differentiates it from a juxtacortical tumor. Axial imaging for differentiation from Brodie abscess, osteoblastoma, stress fracture. Amsterdam: Elsevier; 1993. Most bone tumors are solitary lesions. T2-weighted axial MR image demonstrates high signal intensity of the tumor in the metacarpal bone with extension of a lobulated soft tissue mass. This is an example of progression of an osteochondroma to a peripheral chondrosarcoma. The zone of transition only applies to osteolytic lesions since sclerotic lesions usually have a narrow transition zone. by Clyde A. Helms The image on the right is of a different patient who has an old NOF that shows complete fill in. Degenerative subchondral cyst: epiphyseal, Chondroid matrix in cartilaginous tumors like enchondromas and chondrosarcomsa. Here a chondrosarcoma of the left iliac bone. Calcifications or mineralization within a bone lesion may be an important clue in the differential diagnosis. Usually it is a lesion of childhood or young adults. Less common: Fibrous dysplasia, Brown tumors of hyperparathyroidism, bone infarcts. Aggressive periosteal reaction It is assumed that several tumor-derived growth factors increase osteoblast activity while osteoclast activity is restricted 3,4. Signed by [redacted] on 1/17/2020 11:42 AM Narrative Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements. 1. This is especially true when the injury involves the spine, hip, knees, or ankle. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. 12. Click here for more information about bone island. 6. 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. For those that are possibly cancerous, a biopsy is conducted to identify it. (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 ). Small zone of transitionA small zone of transition results in a sharp, well-defined border and is a sign of slow growth.A sclerotic border especially indicates poor biological activity. This part corresponds to a zone of high SI on T2-WI with FS on the right. Here a 44-year old male with a mixed lytic and sclerotic mass arising from the fifth metacarpal bone. Differentiating a bone infarct from an enchondroma or low-grade chondrosarcoma on plain films can be difficult or even impossible. Fibrous dysplasia, enchondromas, EG, Mets and myeloma, Hyperparathyroidism, Infection. MR usually shows a large amount of reactive changes in bone and soft tissue. Most commonly encountered bone tumor in the small bones of the hand and foot. Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. 2021;13(22):5711. 7. Cartilaginous tumors in particular chondrosarcoma may show endosteal scalloping, while a bone infarct does not. Osteoid osteoma (2) Eosinophilic Granuloma and infections should be mentioned in the differential diagnosis of almost any bone lesion in patients < 20 years. Mild mass effect on adjacent lung, diaphragm, and liver. Peripheral chondrosarcoma, arising from an osteochondroma (exostosis). The epiphysis, metaphysis and diaphysis may be involved. Growth has been demonstrated well after skeletal maturity. Fibro-osseous lesion like fibrous dysplasia. Cortical destruction is a common finding, and not very useful in distinguishing between malignant and benign lesions. Sclerosis is usually the most prominent finding in subacute and chronic osteomyelitis. 13. A benign type of periosteal reaction is a thick, wavy and uniform callus formation resulting from chronic irritation. 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. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed i Osteosarcoma (2) Macedo F, Ladeira K, Pinho F et al. Polyostotic lesions Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. in Ewing's sarcoma or lymphoma. Benign lesion consisting of well-differentiated mature bone tissue within the medullary cavity. Radiographs are specific but suffer from low sensitivity 1. Centrally there is an ill-defined osteolytic area. A Codman's triangle refers to an elevation of the periosteum away from the cortex, forming an angle where the elevated periosteum and bone come together. Malignant transformation Click here for more examples of eosinophilic granuloma. ImageBenign periosteal reaction in an osteoid osteoma.Large arrow indicates solid periosteal reaction.Small arrow indicates nidus. Most commonly originate from prostate and breast cancer and less frequently from lung cancer, lymphoma or carcinoid. Henry Ford Hospital, Neuro Surgery, MI, 1999 Universitat Dusseldorf, Neuro Surgery, 1990 Universitaire Instelling Antwerpen, Neuro Surgery, 1983 The sagittal T1WI and Gd-enhanced T1W-image with fatsat show a large tumor mass infiltrating a large portion of the distal femur and extending through the cortex into the soft tissues. On CT sclerotic bone metastases typically present as hyperdense lesions, but display a lower density than bone islands 5. Causes include trauma, infection, autoimmune diseases, inflammatory diseases, spinal degeneration, congenital malformations, and benign or cancerous tumors. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. 1 When the vertebral lesion has no benign features, especially in the older adult patient, metastatic disease is always a significant consideration. Large lesions tend to expand into both areas. (A) Small radiolucent lesion exhibiting a thin sclerotic border (arrow) is present in the lateral cortex of the distal tibia of a 13-year-old boy. Accordingly, growth of osteochondromas is allowed until a patient reaches adulthood and the physeal plates are closed. 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. Infection may be well-defined or ill-defined osteolytic, and even sclerotic. A T1w/T2-weighted (T2w) hypointense nonexpansile lesion is seen involving the sacrum (asterisk). Uncommonly it can be difficult to differentiate a stress fracture from a pathologic fracture, that occurs at the site of a bone tumor. Bone metastases are the most common malignancy of bone of which sclerotic bone metastases are less common than lytic bone metastases. Classic ground glass appearance of the bone. Consider peripheral chondrosaroma in growing osteochondromas with or without pain after closure of the physeal plate. Should be included in the differential diagnosis of young patient with multiple lucent lesions (Langerhans cell histiocytosis). When a reactive process is more likely based on history and imaging features, follow-up is sometimes still needed. Gadolinium is usually minimal or absent (see right image). Fisher C, DiPaola C, Ryken T et al. In skeletally mature patients, GCTs begin in the metaphysics and extend deep to the subchondral bone plate of the articular surface. Sclerotic bone lesions are rare; commonly affects the axial skeleton (pelvis, spine, skull, ribs) and the patients are often symptomatic as opposed to the patients with lytic lesions who rarely have any symptoms. 5. The lesson here is that when we are dealing with a very common disorder, even its less common presentations will be seen commonly. Another approach to the differential diagnosis of sclerotic bone lesions is to use the mnemonic I VINDICATE, which means 'I clear myself from accusation'. This benign reactive process is most commonly found adjacent to the cortex of phalanges of hands or feet (75%). Distinction of Long Bone Stress Fractures from Pathologic Fractures on Cross-Sectional Imaging: How Successful Are We? 2. (2007) ISBN:0781765188. Contrast-enhanced T1-weighted MR image demonstrates heterogeneous enhancement of the mass with extensive surrounding edema. Growth of the osteochondroma takes place in the cap, corresponding with normal enchondral growth at the growth plates. 8. This could very well be an enchondroma.
