Uncommon Manifestations of Intervertebral Disk Pathologic Conditions. Epidemiology The vast majority of discal cysts, as rare as they are, have been reported in males (M:F 9:1), typically of Asian ethnicity 1,2. Diagnostic criteria according to the WHO classification of soft tissue and bone tumors (5th edition)1: a multicystic bone lesion with fluid-fluid levels on imaging, histological evidence that cyst walls are composed of fibroblasts, osteoclastic giant cells, and hemosiderin pigment as well as proof of new bone formation. The spinal column is not a common site for SBC [4]. ABC accounts for the 'A' in the popular mnemonic for lucent bone lesions FEGNOMASHIC. 2005;23(27):6756-62. This rare pathognomic radiologic finding is known as fallen fragment sign (12). Lesions coming from the cervico-brachial plexus are expected to be found in more paraspinal locations.

A single vertebral surgical approach for spinal extradural meningeal cysts spanning multiple vertebral segments by auxiliary neuroendoscope. Notice that many benign osteolytic lesions that are . Welcome, VIN Public! Radiographs demonstrate a sharply defined, expansile solitary lucent bone lesion, with thin-walled cavities 3. Percutaneous treatment with fibrosing agents has also been performed, either in isolation or as a precursor to surgical excision 3,11,12. Compared to the other lesions in this list, aneurysmal bone cysts are markedly expansile (hence, "aneurysmal") and have a thin cortical shell. The etiology of these discal cysts remains uncertain, but they are believed to occur due to traumatic disruption of the annulus with subsequent accumulation of fluid, which forms a surrounding pseudocapsule 1,2. Although Bloodgood first recognized simple bone cysts as a distinct disease entity in 1910, Jaffe and Lichtenstein (1) were the first to provide a detailed description of the simple vertebral bone cyst in 1942. Corticosteroid injection had been described for lesion in the peripheral skeleton can be considered when the risk of fracture is low [30, 23]. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Gaillard F, Hacking C, El-Feky M, et al. Moreover, our patient was 26 years old, well above the usual age for lesions in the long bones (7). There is vivid enhancement of the mass. Microscopic examination revealed mature fat cells, muscle fibers, and connective tissue fragments of the tendons that showed chondroid metaplastic foci (Fig 6A). This paper describes a fourth case of vertebral sarcoidosis and emphasizes the radiographic features of the disease. Top 3 Differentials in Radiology, A Case Review. The vertebral body and vertebral vessels are not involved. Curtis A. Dickman, Michael Fehlings, Ziya L. Gokaslan. MRI of Bone and Soft Tissue Tumors and Tumorlike Lesions. It should be stated that if any sign of malignant lesion was encountered, the surgery would have stopped and only biopsy would have been performed. In conclusion, this study presents two cases of SBCs and reviews the literature. 5). The vertebral endplate: disc degeneration, disc regeneration. Vertebral pneumatocyst. There are multiple internal septations with enhancement and fluid-fluid levels. The stroma corresponds to septations with fibroblasts, spindle cells, osteoids, and numerous benign giant cells. CT proved to be more useful in the initial assessment and measurement of progress of this disease than conventional radiography and myelography. On rare occasions, this is the result of a pathologic fracture. The post-operative recovery was uneventful, but the child wore a plaster collar for three months. 2004;232(2):522-6. Vertebral body endplatesare anatomically-discrete structures that form the interface between the vertebral bodies and the adjacent intervertebral discs. solitary lucent bone lesion, high T1 or low T1 bone lesion, location within the bone (eccentric, central). Aegerter and Kirkpatrick (11) proposed that the cause of the simple bone cysts is post-traumatic and posthemorrhagic, except the ones in the long bones. Herrero, Carlos Fernando P. S., Garcia, Sergio Britto, Garcia, Luis Vicente, Aparecido Defino, Helton Luiz. On follow up, these lesions can change into fluid-filled cavities and eventually become granulation tissue 2. As bone growth progresses the cyst loses its connection to the physis migrating into the diaphysis and subsequently healing. The patient underwent surgery and excisional biopsy through the posterior approach. Differential Diagnosis in Orthopaedic Oncology. They have been traditionally treated operatively with intralesional curettage or excision or complete en bloc excision with bone grafting are options 3.

Radiographs and nonenhanced CT images show lytic lesions producing cortical thinning and expansion with a destructive sacral or vertebral mass. Meningiomas and hemangiomas usually reveal a solid and rather homogeneous post . Computed tomography (CT) showed a multi-lobulated osteolytic lesion within the T12 body with extension to the right pedicle and transverse process (Fig. Simple bone cysts usually lead to fracture of the bone; therefore, some of these fractures may cause the migration of a fractured bone tissue into the cystic cavity. The synovial cyst is a lesion that can be treated by z-joint intra-articular injections as an alternative to surgery. Causes of Subchondral Bone Cysts. SBCs were found in cervical (n=10, 47.6%), lumbar (n=10, 47.6%) and thoracic (n=1, 4.8%) regions. Steven P. Meyers. Radiographic evaluation of vertebral body lesions has three goals: (1) to identify lesions, (2) characterize lesions and generate a differential diagnosis, and (3) assess for associated complications (in particular cord compression) and treatment response. The vertebra is divided anatomically into the vertebral body anteriorly and the neural arch posteriorly. At present, there is no gold standard for treatment for SBCs and Surgery may not be the optimal treatment for patients except for large lesions or pathologic fracture [21]. We present a simple bone cyst involving the C4 vertebra of a 26-year-old female patient. Aneurysmal bone cysts commonly present with pain and swelling. Aneurysmal bone cysts do not express H3.3pGly34Trp, a feature that can be used to differentiate them from giant cell tumors of bone with aneurysmal bone cyst-like changes 1. Although now generally considered as part of the vertebral body, historically they had been grouped with the intervertebral disc 3. Body and right pedicle and transverse process, Copyright 2023 Oxford University Press and JSCR Publishing Ltd. Vertebral endplate changes were redefined with the advent of MRI, which enabled visualization of previously unrecognized alterations in marrow signal. They are common in patients younger than 30 years, with a slight female predominance. An aneurysmal bone cyst is an expansile osteolytic lesion with a thin wall, containing blood-filled cystic cavities.

The vertebral endplate capillaries are tiny branches of interosseous arteries that ramify throughout the vertebral body. Albany Medical Center Medical Imaging is a medical group practice located in Albany, NY that specializes in Emergency Medicine and Radiology. Histologically aneurysmal bone cysts are characterized by the following 1,6: blood-filled cystic spaces separated by septa containing woven bone, bland fibroblasts, and multinucleated osteoclastic giant cells, the woven bone follows the border of the fibrous septa, bordered by osteoblasts. Welcome VIN Logout Hence, we used all these three imaging techniques to make a complete diagnosis. Soft Tissue and Bone Tumours. Radiology. A: The WHO diagnostic criteria of aneurysmal bone cysts are: - a multicystic bone lesion with fluid-fluid levels on imaging; - histologic evidence of new bone formation with fibroblasts, osteoclastic giant cells, and hemosiderin pigment in the cyst walls. MR images show a multiloculated mass of heterogeneous signal intensity that usually has blood products within (7). Unable to process the form.

The tumor has a heterogeneous appearance on both T1 and T2-weighted MR, with focal areas of high T1 signal, presumably representing blood. Wilkins R. Unicameral Bone Cysts. If fractured the bone usually heals normally 5. During the active phase, the cyst remains adjacent to the growth plate. Thank you for your interest in spreading the word on American Journal of Neuroradiology. . Two cases include a 24 year-old male and 26 year-old male with vertebral body lesion of T12 and L5 vertebrae,retrospectively. In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. When all of the radiologic findings were assessed, we concluded that the lesion had the characteristic radiologic appearance of a simple bone cyst. AJNR Am J Neuroradiol. Centrally flow voids are present, indicating a hypervascular nature. Primary bone tumors of the spine are much less common than secondary metastatic disease: plasmacytoma/multiple myeloma: most common primary bone cancer, chordoma: more common in sacrum (50%) and clivus (35%) than cervicothoracic vertebral column (15%), Langerhans cell histiocytosis(eosinophilic granuloma). According to the radiologic findings, the lesion was identified as a simple bone cyst, and the diagnosis was verified by surgical and histopathologic examinations. Haaga, John R. 1945-. An otherwise healthy 26-year-old female patient presented with a 1-year history of neck pain radiating to both upper extremities. Another suggestion is that venous obstruction of interstitial fluid drainage might be the cause (10). {"url":"/signup-modal-props.json?lang=us\u0026email="}, Gaillard F, Hacking C, Weerakkody Y, et al. Aneurysmal bone cysts are benign giant cell-rich lesions of unknown cause and are sometimes difficult to distinguish from other bone tumors 1-6. Locations include 1,2,5: proximal humerus: most common 50-60% proximal femur: 30% other long bones occurrence elsewhere is relatively uncommon, and usually occurs in adults spine: usually posterior elements 3). The term aneurysmal is derived from its radiographic appearance. On x-rays the facet joints and interspinous distances are usually widened and the disk space may be narrowed. (2015) Folia morphologica. A: Histological features of aneurysmal bone cysts usually show blood-filled spaces without endothelial lining between fibrous stromata. Gas measures about -580 to -1000 HU in density 3. In some instances, surgery with curettage and bone grafting is required. Surg Neurol Int. Wood W. Lovell, Robert B. The specimen was sent for pathologic examination. Case 1, Histopathological examination of the patient. Cross-sectional imaging may be required when lesions are in unusual . The reported peak is between 3 and 14 years of age, with the mean age at diagnosis being approximately 9 years. Published by Oxford University Press and JSCR Publishing Ltd. All rights reserved. The differential diagnosis for bone tumors is dependent on the age of the patient, with a very different set of differentials for the pediatric patient. Giant cell tumors have been described at the ends of long bones, characteristically around the knee. A systematic approach is useful for recognizing tumors of the spine with characteristic features such as bone island, osteoid osteoma, osteochondroma, chondrosarcoma, vertebral angioma, and aneurysmal bone . Vertebral body endplates are anatomically-discrete structures that form the interface between the vertebral bodies and the adjacent intervertebral discs.
