Amsterdam: Elsevier, 1993. Click here for more examples of enchondromas. Here a partially calcified mass against the proximal humerus with involvement of the cortical bone on an axial CT image. Matching the degradation rate of the materials with neo bone formation remains a challenge for bone-repairing materials. Solitary lucent lesions in bone with a distinct margin are generally called "geographic" lesions, whether or not they have a sclerotic rim. Spinal lesions are commonly spotted on imaging tests. 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. Clinically relevant bone metastases are a major cause of morbidity and mortality for prostate cancer patients. The differential for multifocal lesions happens to be identical to that for focal lesions. 10. At the periphery of the infarct a zone of relative high signal intensity on T2WI may be found. Presentation: pain, mass, pathologic fracture. 2021;216(4):1022-30. The diagnosis was fibrous dysplasia. Unable to process the form. Yes, it is possible to have a clear lumbar puncture and still have Multiple Sclerosis (MS). Here a rather wel-defined eccentric lesion which is predominantly sclerotic. 2nd most common primary bone tumor and highly malignant. 33.1a) and sagittal short tau inversion recovery (STIR; Fig. 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. 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 Here Melorrheostosis of the ulna with the appearance of candle wax. Radiographs are specific but suffer from low sensitivity 1. 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. If you can find evidence of subchondral collapse or the typical lucent/sclerotic appearance of the necrotic bone in the weight-bearing bone, then osteonecrosis becomes a much more likely diagnosis. This occurs in early knee osteoarthritis and indicates the potential for cartilage loss and misalignment of a knee compartment. Here a lesion in the epiphysis, which was the result of post-traumatic osteonecrosis. The cause of sclerotic lesions was assessed histologically or by clinical and imaging follow-up. 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 Typical bone metastases are osteolytic (87.5%), with medullary origin (91.6%), and they cannot be distinguished from other osteolytic metastases on the basis of imaging criteria alone. Oncol Rev. The benign type is seen in benign lesions such as benign tumors and following trauma. Differential diagnosis Systematic Approach of Sclerotic Bone Lesions Basis on Imaging Findings. Infection with a multilayered periosteal reaction. 3. Complete envelopment may occur. Both imaging modalities achieved only a moderate correlation with DEXA. Here a chondrosarcoma of the left iliac bone. The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. Growth has been demonstrated well after skeletal maturity. 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. 105-118. 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. The use of PET/CT imaging with new radiotracers enables a non-invasive assessment of the presence of the target of treatment in the whole body and provides the possibility to combine functional information with anatomical details. MR usually shows a large amount of reactive changes in bone and soft tissue. Both of these entities may have an aggressive growth pattern. Osteoid matrix The chondroid matrix is of a variable amount from almost absent to dens compact chondroid matrix. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. 2. . 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. The differential diagnosis of bone lesions that result in bony sclerosis will be given. Differentiating between a diaphyseal and a metaphyseal location is not always possible. Here an image of a patient with chronic osteomyelitis. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail. Sclerosing bone dysplasias are skeletal abnormalities of varying severity with a wide range of radiologic, clinical, and genetic features. 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. FD is often purely lytic, but may have a groundglass appearance as the matrix calcifies. MRI of the sacrum: axial T1-weighted (T1w; Fig. Sclerosis is present from either tumor new bone formation or reactive sclerosis. Mark Blumenkehl, MD is a specialist in Gastroenterology whose practice locations include: Detroit, Sterling Hgts Contrast-enhanced T1-weighted MR image demonstrates heterogeneous enhancement of the mass with extensive surrounding edema. On CT sclerotic bone metastases typically present as hyperdense lesions, but display a lower density than bone islands 5. ADVERTISEMENT: Supporters see fewer/no ads. They usually affect posterior vertebral elements and their number and size increase with age. Endosteal scalloping of the cortical bone can be seen in benign lesions like Fybrous dysplasia and low-grade chondrosarcoma. (2005) ISBN: 9780721602707 -. Benign lesion consisting of well-differentiated mature bone tissue within the medullary cavity. The zone of transition only applies to osteolytic lesions since sclerotic lesions usually have a narrow transition zone. Polyostotic lesions Differential Diagnosis in Orthopaedic Oncology. The radiograph shows typical bone infarcts in diaphysis and metaphysis of femur and tibia.. On MR imaging bone infarcts are characterized by irregulair serpentiginous margins with low signal intensity on both T1 and T2 WI and with intermediate to high fat signal in the center part. Materials and Methods 33.1d). 1. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. Imaging is often helpful in determining a diagnosis, and it can sometimes make a particular diagnosis nearly certain. The images show on the left a typical osteolytic NOF with a sharp sclerotic border. See article: bone metastases. This benign reactive process is most commonly found adjacent to the cortex of phalanges of hands or feet (75%). Most commonly encountered bone tumor in the small bones of the hand and foot. 6. The major part of the lesion consists of reactive sclerosis. Osteoblastic metastases (2) Isaac A, Dalili D, Dalili D, Weber M. State-Of-The-Art Imaging for Diagnosis of Metastatic Bone Disease. As you can see, by just dropping the items that tend to cause generalized sclerosis, we have generated a fairly good differential for focal lesions. Bone metastases start with the tropism of cancer cells to the bone through different multi-step tumor-host interactions, as described by the . In the table the most common sclerotic bone tumors and tumor-like lesions in different age-groups are presented. Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements. Interventional Radiology). Secondary bone cancer is much more common than primary bone . You may have been surprised to see metastatic disease listed as a leading cause for diffuse sclerotic bones. Intense uptake on bone scintigraphy as we would expect in high grade chondrosarcoma. 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. 7, Behrang Amini, Susana Calle, Octavio Arevalo, Richard M. Westmark, and Kaye D. Westmark, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), on 33 Incidental Solitary Sclerotic Bone Lesion, 27 Approach to the Solitary Vertebral Lesion on Magnetic Resonance Imaging, 28 Diffusely Abnormal Marrow Signal within the Vertebrae on MRI, Incidental Findings in Neuroimaging and Their Management, Radiology (incl. The term bone infarction is used for osteonecrosis within the diaphysis or metaphysis. There is a metastasis, which presents as a subtle sclerotic lesion in the humerus metaphysis. Unable to process the form. The NK cell type is seen as a sheet of soft tissue in the nasal cavity with bone destruction and erosion without any sclerosis. 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. Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. MRI also may detect the nidus, combined with abundant bone marrow and soft tissue edema. A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. Skeletal Radiol. Sclerotic or osteoblastic bone metastases are distant tumor deposits of a primary tumor within bone characterized by new bone deposition or new bone formation. Localisation: femur, tibia, hands and feet, spine (arch). Causes include trauma, infection, autoimmune diseases, inflammatory diseases, spinal degeneration, congenital malformations, and benign or cancerous tumors. Sclerosis is usually the most prominent finding in subacute and chronic osteomyelitis. The homogeneous enhancement in the upper part with edema and cortical thickening are not typical for a low-grade chondrosarcoma. 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. Spine (Phila Pa 1976). In aggressive periostitis the periosteum does not have time to consolidate. Many sclerotic lesions in patients > 20 years are healed, previously osteolytic lesions which have ossified, such as: NOF, EG, SBC, ABC and chondroblastoma. 12. Continue with the MR-images. 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. Bker S, Adams L, Bender Y et al. In 8 of the 24 patients, 17 of 52 new sclerotic lesions (33%) had showed positive uptake on previous bone scans. Hall F & Gore S. Osteosclerotic Myeloma Variants. Not infrequently encountered as coincidental finding at later age. Lesions in the bone are usually identified on radiographic images - chiefly X-rays - but also on CT and MRI scans. Radiologe. In fact, in areas where sickle cell disease is common, this may be the leading cause of diffuse sclerotic bones. diffuse sclerotic metastases to the pelvis, sacrum and femurs. Several genes have been discovered that, when disrupted, result in specific types . Brant WE, Helms CA. However, a specific density range has not been specified for those terms 1. In the active phase there is multilaminar periosteal reaction and bone and soft tissue edema. The zone of transition is the most reliable indicator in determining whether an osteolytic lesion is benign or malignant (1). Ulano A, Bredella M, Burke P et al. {"url":"/signup-modal-props.json?lang=us"}, Gaillard F, Knipe H, Weerakkody Y, et al. Click here for more detailed information about fibrous dysplasia. 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. 7. {"url":"/signup-modal-props.json?lang=us"}, Knipe H, Yap J, Masters M, et al. Check for errors and try again. The pathogenesis of myeloma-related bone disease (MBD) is the imbalance of the bone-remodeling process, which results from osteoclast activation, osteoblast suppression, and the immunosuppressed bone marrow microenvironment. 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. These lesions usually regress spontaneously and may then become sclerotic. 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. At the 1-year follow-up, the lesion was completely stable and no additional follow-up was recommended in the absence of symptoms. Hallmark of osteosarcoma is the production of bony matrix, which is reflected by the sclerosis seen on the radiograph. Sclerotic osteoblastic metastases must be included in the differential diagnosis of any sclerotic bone lesion in a patient > 40 years. Radiographically, GCTs are eccentrically located radiolucent lesions with well-defined lytic 1B margins and geographic bone destruction. Frequently encountered as a coincidental finding and can be found in any bone. Subchondral bone attrition is the flattening or depression of the bone surface that forms part of a joint. Starting on day 28, sclerotic changes surrounding the bone absorption area were detected. However, the exact mechanism that leads to osteoblastic formation is not entirely elucidated. Bone islands can be large at presentation. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . Likewise patients with sclerotic lesions due to various drugs or minerals will tell you what they are taking if you ask them. Typically a NOF presents as an eccentric well-defined lytic lesion, usually found as a coincidental finding. Here some typical examples of bone tumors in the foot: Fundamentals of Skeletal Radiology, second edition 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. Henry Ford Hospital, Neuro Surgery, MI, 1999 Universitat Dusseldorf, Neuro Surgery, 1990 Universitaire Instelling Antwerpen, Neuro Surgery, 1983 AJR 2005; 185:915-924. A popular mnemonic to help remember causes of focal sclerotic bony lesions is: Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Bone scan shows no high activity, opposed to low-grade intraosseous osteosarcoma. This is extremely common in Pagets disease but extremely uncommon with a blastic metastasis. Polyostotic lesions > 30 years Here a patient with a broad-based osteochondroma with extension of the cortical bone into the stalk of the lesion. Classic ground glass appearance of the bone. 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"}. Bone cements such as polymethyl methacrylate and calcium phosphates have been widely used for the reconstruction of bone. Solitary sclerotic bone lesion. Here are links to other articles about bone tumors: Most bone tumors are osteolytic. Most commonly originate from prostate and breast cancer and less frequently from lung cancer, lymphoma or carcinoid. Focal sclerotic bony lesions (mnemonic). You can then customize the above differential for whichever pattern of sclerosis that you see. Notice that the cortical bone extends into the lesion. On the left three bone lesions with a narrow zone of transition. CT of Sclerotic Bone Lesions: Imaging Features Differentiating Tuberous Sclerosis Complex with Lymphangioleiomyomatosis from Sporadic Lymphangioleiomymatosis1. Check for errors and try again. Disappearane of calcifications in a pre-existing enchondroma should raise the suspicion of malignant transformation. In patients > 30 years, and particularly > 40 years, despite benign radiographic features, a metastasis or plasmacytoma also have to be considered Radiologic Atlas of Bone Tumors Magnetic resonance imaging of subchondral bone marrow lesions in association with osteoarthritis. <-Lucent Lesions of Bone | Periosteal Reaction->. Benign periosteal reaction Patients usually have sclerotic bone lesions before and lytic bone lesions after puberty. Sclerotic bone lesions appear exclusively in middle aged black patients. The MR image shows that the lesion has lobulated contours and nodular enhancement. mutation, and both sclerotic and lytic bone lesions together for the first time. Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. Bone Metastases: An Overview. Here on a radiograph the typical calcifications in the chondroid matrix of an enchondroma. This represents a thick cartilage cap. Unable to process the form. Here images of a patient with prostate cancer. A periosteal chondroma may have the same imaging characteristics, however, these are almost always much smaller. Imaging: Ahuja S & Ernst H. Osteoblastic Bone Metastases in Medullary Thyroid Carcinoma. Focal sclerotic bony lesions (mnemonic) Last revised by Daniel J Bell on 18 Feb 2019 Edit article Citation, DOI & article data A popular mnemonic to help remember causes of focal sclerotic bony lesions is: HOME LIFE Mnemonic H: healed non-ossifying fibroma (NOF) O: osteoma M: metastasis E: Ewing sarcoma L: lymphoma I: infection or infarct 2. Strahlenther Onkol. In the group of malignant small round cell tumors which include Ewing's sarcoma, bone lymphoma and small cell osteosarcoma, the cortex may appear almost normal radiographically, while there is permeative growth throughout the Haversian channels. This is an example of progression of an osteochondroma to a peripheral chondrosarcoma. The diagnosis is usually established by a combination of imaging and the known presence of a primary tumor that is associated with sclerotic bone metastases. When you are considering osteonecrosis in your differential diagnosis, look at the joints carefully. Giant cell bone tumors are usually benign (not cancerous) but the malignant form can affect the legs, especially near the knees. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Adamantinoma in case of a sclerotic lesion with several lucencies of the tibia in a young patient. A high grade chondrosarcoma must be considered in the differential diagnosis. The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. by Mulder JD, et al. Sclerotic or blastic bone metastases can arise from a number of different primary malignancies including prostate carcinoma (most common), breast carcinoma (may be mixed), transitional cell carcinoma (TCC), carcinoid, medulloblastoma, neuroblastoma, mucinous adenocarcinoma of the gastrointestinal tract (e.g., colon carcinoma, gastric carcinoma), colon carcinoma, gastric carcinoma), ADVERTISEMENT: Supporters see fewer/no ads. 33.1b), CT scan axial images (c), and bone scintigraphy (d). Enchondroma, the most commonly encountered lesion of the phalanges. It is barely visible within the bone, but an agressive periostitis is seen (arrow). It can differentiate predominantly osteoblastic from osteolytic bone metastases 9 as well as easily demonstrate and assess complications such as pathological fractures or spinal cord compression 2,3. Kimura T. Multidisciplinary Approach for Bone Metastasis: A Review. Bone metastases are the most common malignancy of bone of which sclerotic bone metastases are less common than lytic bone metastases. Cortical destruction (3) The radiographic appearance and location are typical. Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements. 2003;415(415 Suppl):S4-13. Ossifications or calcifications can be present in variable amounts. Click here for more examples of eosinophilic granuloma. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. AJR Am J Roentgenol. 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. In the article Bone Tumors - Differential diagnosis we discussed a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. When considering Pagets disease, it is extremely helpful to note whether there is associated bony enlargement. Multiple myeloma is a hematologic malignancy of plasma cells that causes bone-destructive lesions and associated skeletal-related events (SREs). Symptoms include pain, abnormal sensations, loss of motor skills or coordination, or the loss of certain bodily functions. Density measurements on CT scan revealed greater than 1,000 HU throughout the lesion. Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3. It is true that the usual appearance of skeletal metastases is that of focal lesions diffuse sclerosis occurs in only a small fraction of cases of skeletal metastases. Based on the morphology and the age of the patients, these lesions are benign. A sclerotic border especially indicates poor biological activity. WSI digital slide: https://kikoxp.com/posts/4606. DD: Ganglion cyst, osteomyelitis, GCT, ABC, enchondroma. NOF, fibrous dysplasia, multifocal osteomyelitis, enchondromas, osteochondoma, leukemia and metastatic Ewing' s sarcoma. Macedo F, Ladeira K, Pinho F et al. Check for errors and try again. The use of radiological imaging in medical care dates back to 1895 when Subungual exostoses are bony projections which arise from the dorsal surface of the distal phalanx, most commonly of the hallux. Occasionally slowly enlargement can be seen. Peripheral chondrosarcoma, arising from an osteochondroma (exostosis).
