Benign periosteal reaction BackgroundCongenital generalized lipodystrophy (CGL) is a rare disease. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. Wide zone of transition Ali Mohammed Hammamy R, Farooqui K, Ghadban W. Sclerotic Bone Metastasis in Pulmonary Adenocarcinoma. It is nost commonly located on the posterior side of the distal meta-diaphysis of the femur. A lucent, well-circumscribed lesion is seen with a surrounding thin sclerotic cortical rim on plain radiographs [ Figure 4 ]. Osteosarcoma, chondrosarcoma, and Ewing's sarcoma are the most common types of bone cancer. Sclerotic metastases arise from . RT @JMGardnerMD: 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. Frequently encountered as a coincidental finding and can be found in any bone. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. When considering Pagets disease, it is extremely helpful to note whether there is associated bony enlargement. Small osteolytic lesion (up to 1.5 cm) with or without central calcification. Rib lesions detected on bone scintigraphy often require further characterization with radiography or CT to improve specificity (Figs. Sclerotic bone lesions are commonly detected by abdominal MRI in children with tuberous sclerosis complex. MRI shows large tumor within the bone and permeative growth through the Haversian channels accompanied by a large soft tissue mass, which is barely visible on the X-ray. Complete envelopment may occur. 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. Typical presentation: central lesion in metaphysis or diaphysis with a well defined serpentiginous border. Biopsy revealed dedifferentiated chondrosarcoma. Lippincott Williams & Wilkins. Calcifications in chondroid tumors have many descriptions: rings-and-arcs, popcorn, focal stippled or flocculent. If the patient had fever and a proper clinical setting, osteomyelitis would be in the differential diagnosis. Detection of a solitary sclerotic bone lesion on CT or plain radiograph often creates a diagnostic dilemma. Not infrequently encountered as coincidental finding at later age. Consider progression of osteohondroma to chondrosarcoma when cartilage cap measures > 10 mm. Ossification in parosteal osteosaroma is usually more mature in the center than at the periphery. 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. (2007) ISBN:0781765188. 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. There are two tumor-like lesions which may mimic a malignancy and have to be included in the differential diagnosis. Osteomyelitis is a mimicker of various benign and malignant bone tumors and reactive processes that may be accompanied by reactive sclerosis. In juxta-articular localisation, the reactive sclerosis may be absent. 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. Bone Metastases: An Overview. At Henry Ford Orthopaedics in Chelsea our mission is to provide personalized treatment plans specific to each patient, to ensure the best possible outcome. Etiology Notice that in all three patients, the growth plates have not yet closed. 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. 1991;167(9):549-52. 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. Both imaging modalities achieved only a moderate correlation with DEXA. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. The differential diagnosis of bone lesions that result in bony sclerosis will be given. Secondary bone cancer is much more common than primary bone . Skeletal Radiol. 33.1b), CT scan axial images (c), and bone scintigraphy (d). Infections, a common tumor mimicker, are seen in any age group. Radiology. 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). Osteoblastic metastatic disease (see Table 33.1): More often multiple with increased uptake on bone scan. A periosteal chondroma may have the same imaging characteristics, however, these are almost always much smaller. Endosteal scalloping of the cortical bone can be seen in benign lesions like Fybrous dysplasia and low-grade chondrosarcoma. These are inert filled-in non-ossifying fibromas. Check for errors and try again. At the periphery of the infarct a zone of relative high signal intensity on T2WI may be found. 2020;60(Suppl 1):1-16. 2016;207(2):362-8. Reference article, Radiopaedia.org (Accessed on 02 Mar 2023) https://doi.org/10.53347/rID-21100, Mnemonic for focal sclerotic lesions (mnemonic). Distinct phenotypes are described: osteoblastic, the more common osteolytic and mixed. 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"}. 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. This is consistent with the diagnosis of a reactive process like myositis ossificans. Sclerotic bone lesions appear exclusively in middle aged black patients. Sclerotic bone metastases. Because of the large dimensions with soft tissue extension on plain radiograph and axial T2-weighted MR image, a high grade chondrosarcoma was suspected. Here some typical examples of bone tumors in the foot: Fundamentals of Skeletal Radiology, second edition 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. A Novel Classification System for Spinal Instability in Neoplastic Disease: An Evidence-Based Approach and Expert Consensus from the Spine Oncology Study Group. There are calcified strands within the soft tissues. Here a patient with a mineralized mass in the soft tissues. 7, Behrang Amini, Susana Calle, Octavio Arevalo, Richard M. Westmark, and Kaye D.

Macedo F, Ladeira K, Pinho F et al. Differentiation of Predominantly Osteoblastic and Osteolytic Spine Metastases by Using Susceptibility-Weighted MRI. 2016;207(2):362-8. 2019;290(1):146-54. A bone island larger than 1 cm is referred to as a giant bone island (12). Brant WE, Helms CA. 5. Aggressive periosteal reaction BallooningBallooning is a special type of cortical destruction.In ballooning the destruction of endosteal cortical bone and the addition of new bone on the outside occur at the same rate, resulting in expansion. diffuse sclerotic metastases to the pelvis, sacrum and femurs. Bone cyst is one of the manifestations of CGL with AGPAT2 mutation. Teaching Point: Metastasis is the most common malignant rib lesion. 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. DD: juxtacortical chondrosarcoma, parosteal osteosarcoma. W. B. Saunders company 1995, by Mark J. Kransdorf and Donald E. Sweet 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 Many sclerotic lesions in patients > 20 years are healed, previously osteolytic lesions which have ossified, such as: NOF, EG, SBC, ABC and chondroblastoma. 33.1a) and sagittal short tau inversion recovery (STIR; Fig. In this case, because of the increased uptake on bone scintigraphy, a follow-up MRI was recommended at 6 and 12 months. Bone metastases are the most common malignancy of bone of which sclerotic bone metastases are less common than lytic bone metastases. Here a chondrosarcoma of the left iliac bone. 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. Mirels H. Metastatic Disease in Long Bones: A Proposed Scoring System for Diagnosing Impending Pathologic Fractures. 105-118. The homogeneous pattern is relatively uncommon compared to the heterogeneous pattern. Uncommonly it can be difficult to differentiate a stress fracture from a pathologic fracture, that occurs at the site of a bone tumor. When you are considering osteonecrosis in your differential diagnosis, look at the joints carefully. Enchondroma, the most commonly encountered lesion of the phalanges. The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. Chordoma is usually seen in the spine and base of the skull. The image shows a calcified lesion in the proximal tibia without suspicious features. A benign type of periosteal reaction is a thick, wavy and uniform callus formation resulting from chronic irritation. In some cases however the osteolytic nidus can be visible on the radiograph (figure). Here, we showed that sBT values are higher in patients presenting 496 with bone loss . See article: bone metastases. Guidelines for the Diagnostic Management of Incidental Solitary Bone Lesions on CT and MRI in Adults: Bone Reporting and Data System (Bone-RADS). Therefore, MRI and bone scan were performed. A sclerotic lesion is an unusual hardening or thickening of your bone. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. Hyperdense oval-shaped lesions with spiculated or paintbrush margins, without distortion of the adjacent bony trabeculae. Focal sclerotic bony lesions (mnemonic). Magnetic resonance imaging of subchondral bone marrow lesions in association with osteoarthritis. 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. 2021;50(5):847-69. The homogeneous enhancement in the upper part with edema and cortical thickening are not typical for a low-grade chondrosarcoma. Osteoma consists of densely compact 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. 6. For example: Differential Diagnosis of Focal or Multifocal Sclerotic Bone Lesions. Continue with the MR-images. These lesions usually regress spontaneously and may then become sclerotic. ( A1,A2) Transversal CT of the skull of a TSC patient and . MRI of the sacrum: axial T1-weighted (T1w; Fig. Rapid growth of the mineralized mass is not uncommon. UW Radiology Sclerotic Lesions of Bone <-Lucent Lesions of Bone | Periosteal Reaction-> What does it mean that a lesion is sclerotic? 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 Laura M. Fayad, Satomi Kawamoto, Ihab R. Kamel, David A. Bluemke, John Eng, Frank J. Frassica and Elliot K. Fishman. Click here for more information about bone island. Radiographic or CT features that suggest malignancy: Use MRI with water-sensitive sequence (T2 FS) to determine cartilage cap thickness. AJR 2000; 175:261-263. 1. 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? The most common appearance is the mixed lytic-sclerotic. Osteochondroma is a bony protrusion covered by a cartilaginous cap. Central location most common with some expansion and cortical thinning. 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. (2007) ISBN: 9780781779302 -. 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. Edema often present in the surrounding bone marrow. Notice the lytic peripheral part with subtle calcifications. On the right T2-WI with FS of same patient.. Most cases of chronic osteomyelitis look pretty nonspecific. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Fundamentals of diagnostic radiology. 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. 12. Bone scintigraphy can be either negative or show limited uptake. Moreover, questions such as the . 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. Polyostotic lesions Oncol Rev. However, the exact mechanism that leads to osteoblastic formation is not entirely elucidated. Park S, Lee I, Cho K et al. These lesions may have ill-defined margins, but cortical destruction and an aggressive type of periosteal reaction may also be seen. Classic ground glass appearance of the bone. However, not all epidermal inclusion cysts involve bone, and some are confined to the subcutaneous tissues. Radiologic Atlas of Bone Tumors 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. Sclerotic bone metastases typically present as radiodense bone lesions that are round/nodular with relatively well-defined margins 3. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail. In an older patient one should first consider an osteoblastic metastasis. Usually typical malignant features including permeative-motheaten pattern of destruction, irregular cortical destruction and aggressive (interrupted) periosteal reaction. Here two patients with a bizar parosteal osteochondromatous proliferation (BPOP), also called Nora's lesion. Results: In 24 patients, 52 new sclerotic lesions observed during therapy were selected for re-evaluation of conventional radiographs and bone scans. Chrondroid tumors are more frequently encountered than bone infarcts. Differential diagnosis Gadolinium is usually minimal or absent (see right image). Patients usually have sclerotic bone lesions before and lytic bone lesions after puberty. 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. Symptoms include pain, abnormal sensations, loss of motor skills or coordination, or the loss of certain bodily functions. This is a routine medical imaging report. A T1w/T2-weighted (T2w) hypointense nonexpansile lesion is seen involving the sacrum (asterisk). Sclerotic bone lesions as a potential imaging biomarker for the diagnosis of tuberous sclerosis complex Authors Susanne Brakemeier 1 , Lars Vogt 2 , Lisa C Adams 2 , Bianca Zukunft 3 , Gerd Diederichs 2 , Bernd Hamm 2 , Klemens Budde 3 , Kai-Uwe Eckardt 3 , Marcus R Makowski 2 4 Affiliations As current recommendations for tuberous sclerosis complex surveillance include renal MR performed i Lippincott Williams & Wilkins. Here a partially calcified mass against the proximal humerus with involvement of the cortical bone on an axial CT image. Detecting a benign periosteal reaction may be very helpful, since malignant lesions never cause a benign periosteal reaction. 2nd most common primary bone tumor and highly malignant. . 1 When the vertebral lesion has no benign features, especially in the older adult patient, metastatic disease is always a significant consideration.
