The patient underwent surgery and excisional biopsy through the posterior approach. 74 (2): 157-68. [ 5, 6] Radiographs usually are adequate for diagnosis and for characterizing typical lesions. Osteoarthritis (OA) is the most common. In support of this theory is the fact that they are primarily encountered in young men, and are often hemorrhagic at surgery 1. Providers Overview Location Reviews Providers 2022. In a recent article, Zener, Alpert, and Klainer (1) reviewed two previously reported cases of sarcoidosis involving the vertebrae in which the diagnosis was established antemortem by biopsy and added a third of their own.

(2012) ISBN:1608319113. Interventional Radiology. 2004;25(7):1291-3. The post-operative recovery was uneventful, but the child wore a plaster collar for three months. Aneurysmal bone cysts have been first described by the American bone pathologist Louis Lichtenstein in 1950 14. Reference article, Radiopaedia.org (Accessed on 18 Jan 2023) https://doi.org/10.53347/rID-23773. 3. The sensitivity to specify a vertebral lesion on an X-ray is difficult as well. The differential diagnosis depends on the modality. Physical examination and laboratory tests were unremarkable with no neurologic deficit. (2009) ISBN:1604062266. Emergency Medicine, Radiology 77 Providers. 2020. Roentgenographic and CT views indicate an osteolytic lesion that results in an expansion and thinning of the surrounding cortical bone. 2 VHs are more frequently found in women, especially in the fourth-to-sixth decades of life. Giant cell tumors have been described at the ends of long bones, characteristically around the knee. Body and right pedicle and transverse process, Copyright 2023 Oxford University Press and JSCR Publishing Ltd. Bone mineral density in cystic fibrosis: benefit of exercise capacity. 9). To our knowledge, only four were in cervical vertebrae (36), and the rest were in lumbar vertebrae (2, 4). CT could precisely show and localize all niduses, and calcification was always detected. 2. Our goal was to present two cases of SBC who were referred to our department of spine surgery and review the literature. Komiya S, Minamitani K, Sasaguri Y, Hashimoto S, Morimatsu M, Inoue A.

A: Surgical resection or curettage of the tumor and bone graft with or without adjuvant treatment, including cryotherapy, sclerotherapy, radionuclide ablation, radiotherapy, selective arterial embolization, and minimally-invasive intervention radiology treatment. Pediatr Radiol. Fig. The lesion appeared homogeneous and hyperintense on axial T2*-weighted images, and no blood degradation products were observed (Fig 4). 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 histopathology showed a pattern compatible with an aneurysmal bone cyst. The etiology and pathogenesis are unknown 8,10. Mosby. [2] According to one study, they have been identified in about 11% of patients at general autopsy. The most frequent sites are proximal humerus and proximal femur [1, 3]. New York Downtown Hospital is a medical group practice located in New York, NY that specializes in Physician Assistant (PA) and Diagnostic Radiology. They are common in patients younger than 30 years, with a slight female predominance. Diagnostic Neuroradiology. The reported peak is between 3 and 14 years of age, with the mean age at diagnosis being approximately 9 years. 15. occupying most of the height of the L2 vertebral body (Figure 2). CT proved to be more useful in the initial assessment and measurement of progress of this disease than conventional radiography and myelography. On CT aneurysmal bone cysts are characterized as lucent bone lesions with a mean density higher than fat 7. Harry B. Skinner. 2016; 88 . (2006) European Spine Journal. Active unicameral bone cysts occur most frequently between the ages of 1 and 10 years. Vertebral body origin intraosseous hemangioma metastases Paget disease multiple myeloma osteonecrosis vertebral body osteomyelitis lymphoma plasmacytoma g. Differential diagnosis of vertebral lesions is very wide. 2015;101(1):S119-27. Primary bone tumors of the spine are much less common than secondary metastatic disease: plasmacytoma/multiple myeloma: most common primary bone cancer Epidural extension may also be detected. Embolization is another option 3. The vertebral body and vertebral vessels are not involved. The imaging evaluation includes computed tomography (CT), myelogra-phy and magnetic resonance imaging (MRI). WHO Classification of Tumours, 5th Edition. ADVERTISEMENT: Supporters see fewer/no ads. To date, 10 cases of simple bone cysts have been reported in the literature (2), and those bone cysts involved vertebral bodies (three), spinous process (three), lamina (one), pedicle (one), both spinous processes and lamina (one), and all components of the vertebrae (one) (26). Case 1, Axial CT scan of twelfth thoracic spine vertebrae. (2014) ISBN: 9781907816222 -. show answer. Both cases were managed with surgery, the cavity was filled with bone graft and posterior spinal fusion and instrumentation with pedicle screws, and rods were carried out. 8. 2. Treatment is not always required and discal cysts have been reported to spontaneously regress 1. X-ray and computed tomography (CT) characterize by expansile osteolytic lesions with thin sclerotic margins and fluid lines. hemangioma, synovial cyst (10,11), abscess and epidural hematoma. Lateral radiograph of the cervical vertebrae. During the active phase, the cyst remains adjacent to the growth plate. General imaging differential considerations include 8,10: giant cell tumor of bone:usually older, extending to the articular surface, non-ossifying fibroma: eccentric, cortical base, aneurysmal bone cyst (ABC): usually eccentric, differential diagnosis of expansile lytic lesions without cortical destruction of bone. Note the thinning of the cortical bone. The patient underwent surgery to remove the suspected simple bone cyst in the C4 vertebra. Most of the simple bone cysts are asymptomatic, unless they come with pathologic fracture. On MRI, the differential is much shorter, especially when age, location and plain film appearance are taken into account. 1). Summary of 2 new cases and 21 reported cases of bone cyst of lumbar vertebral body. 2005;26(1):30-3. Published by Oxford University Press and JSCR Publishing Ltd. All rights reserved. 120 (Pt 1): 49-68. Diehn FE, Maus TP, Morris JM et-al. Vertebral metastasesare significantly more common than primary bone tumors, especially in an older patient or one with known primary disease elsewhere. Lesions can enlarge in size 1. Aneurysmal bone cysts commonly present with pain and swelling. They may occur in all parts of the skeleton and particularly involve the metaphysis of long bones (5, 7) but occasionally involve spine, especially cervical and thoracic regions. If you, or your child, have been diagnosed with aneurysmal bone cyst and want to pursue minimally invasive treatment, call our Interventional Coordinator at (614) 722-2375 to set up a consultation with an Interventional Radiologist. They are constituted peripherally by an epiphyseal bone ring and centrally by a cartilaginous layer. Results Radiography detected 87.1% (27/31) of the lesions; WBBS demonstrated increased radionuclide activity in all the lesions. Vertebral endplate changes were redefined with the advent of MRI, which enabled visualization of previously unrecognized alterations in marrow signal. The patient underwent surgery and the lesion was extracted through the right pedicle and the remaining cavity was filled with an autologous bone graft from the iliac crest and right-side posterior fusion was done from L4 to L5 (Fig. In the case of our patient, the lesion did not cause any such fracture in the bone. 2000;8(4):217-24. 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. Imaging technology precisely guides minimally invasive procedures with needles, catheters and other devices. It may be asymptomatic, and hence the incidence is unknown. Such tumors can affect the spine, particularly the posterior elements. Unicameral bone cyst on bone scintigraphy tends to appear as foci of photopenia (cold spot). Aneurysmal bone cysts display cytogenetic rearrangements of the USP6 gene. J Am Acad Orthop Surg. CT and MR imaging were also used to determine the extent of the lesions and detect possible complications such as fractures. Although roentgenography is usually adequate to identify the simple bone cyst, CT and MR imaging should be used for diagnosis of lesions in anatomically complex locations such as the vertebrae. Physical examination was unremarkable except for tenderness over the lower thoracic spine. 4. 5. As the lesion becomes inactive it migrates away from the growth plate (normal bone is formed between it and the growth plate) and it gradually resolves 3,5. This rare pathognomic radiologic finding is known as fallen fragment sign (12). No enhancement was observed on T1-weighted images following contrast medium administration (Fig 5). The larger posterior part of the vertebral body is displaced backward into the spinal canal. They are typically intramedullary and active cysts are found in the metaphysis of long bones, abutting the growth plate 1. There have been 21 cases of SBCs in English literature, and only 8 cases have been reported in the vertebral body. giant cell tumors (GCT), chondroblastoma, simple bone cystsand telangiectatic osteosarcomas). show answer. MRI is required for assessment of these lesions. Study design: Case report. 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. Depending on the type of surgery. The patient underwent surgical resection of the tumor. Hence, we used all these three imaging techniques to make a complete diagnosis. Most patients are between 20 and 40 years old. A 26-year-old male presented with pain over the lower lumbar area. (2012) ISBN: 9789350258835 -. Society of Skeletal Radiology- White Paper. 2020;11:274. On rare occasions, this is the result of a pathologic fracture. Breakage of a cyst can trigger an immunological reaction from the host, sometimes leading to an anaphylactic shock. show answer. 4). Gamanagatti S, Ghosh A, Singh A, et al. Logout.

SBC is a rare benign lesion in the spine and it should be considered in the differential diagnosis when suggested by radiologic investigations. 1. The most common differential diagnoses for SBC are aneurysmal bone cyst, brown tumor (hyperparathyroidism), infection and less commonly giant cell tumor. They are constituted peripherally by an epiphyseal bone ring and centrally by a cartilaginous layer. AJR Am J Roentgenol. The definitive diagnosis of aneurysmal bone cysts is based on a combination of typical radiological and pathological features. Thank you for your interest in spreading the word on American Journal of Neuroradiology. Alanazi O, Alshebromi A, Albaz A, Bassi M. Thoracic Spine Aneurysmal Bone Cyst Causing Paraplegia in a Child: A Case Report. A case of a simple bone cyst in the spinous process of the fourth cervical vertebra in a 26-year-old woman is reported. Thoracolumbar injury Adam Flanders MRI Imaging at 0.5 Tesla. In the spine, the most typical site of localization is the sacrum; other vertebral segments are rarely involved (7). Spinal aneurysmal bone cysts nearly always arise in the posterior vertebral arch but frequently extend into the ipsilateral pedicle and vertebral body, epidural space, or adjacent neural foramen (see Figs. (d) Retrolisthesis of less than a third of the length of the vertebral body is a feature of unilateral facet dislocation They are most common at cervical levels. If there is a fracture through this lesion a dependent bony fragment may be seen, and this is known as the fallen fragment sign. Radiographs and nonenhanced CT images show lytic lesions producing cortical thinning and expansion with a destructive sacral or vertebral mass. The differential diagnosis for a vertebral body massis broad and may range from a completely benign bone island to a malignant primary bone tumor. Reference article, Radiopaedia.org (Accessed on 18 Jan 2023) https://doi.org/10.53347/rID-34279. 2003;180(6):1681-7. The end plates (zones of provisional calcification) maintain normal mineralization, and so appear strikingly dense compared to adjacent osteoporotic bone. (2011) ISBN: 9781451111750 -. This case illustrates the radiological findings of an aneurysmal bone cyst with the typical MRI fluid-fluid levels and septations separating the cysts. The laboratory tests including complete blood count, renal function tests, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, serum calcium, serum phosphorus and parathyroid hormone were all within normal limits. at last follow-up male was well. Rarely, they are truly multiloculated, which can occur after repeated fractures 3,10. 2016;36 (3): 801-23. Unable to process the form. The patient was asymptomatic and the beginning of bony healing was evident. These cysts are most commonly found within the vertebral bodies, iliac bones or sacrum. Kransdorf M & Sweet D. Aneurysmal Bone Cyst: Concept, Controversy, Clinical Presentation, and Imaging. Fibrous dysplasia and eosinophilic granuloma more commonly present as osteolytic lesions, but they can be sclerotic. The cysts are of a variable signal, with a surrounding rim of low T1 and T2 signals. The previously termed 'giant lesion of small bones' features the same morphological features as the solid subtype of aneurysmal bone cyst 1. They may occur in any bone, most commonly long bones. Vertebral body mass: differential diagnosis, Differential diagnosis of a vertabral body mass, 1. Simple bone cysts are found in the metaphysis of long tubular bones in 9095% of cases, and 565% of such cysts involve the proximal humerus; 2530%, the femur; and the rest, the proximal tibia, fibula, radius, ulna, ileum, patella, rib (8), and calcaneus (9). (2003) ISBN: 9780071387583 -, 6. 10. WHO Classification of Tumours Editorial Board. Difficult to detect, but sometimes gas lucencies are seen within the vertebral bodies. 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]. Differential Diagnosis in Orthopaedic Oncology. Disc cysts have been most commonly reported at the L4/5 level 1. The diagnosis of spinal SBC may be difficult and delayed until operative treatment when it is confirmed by histological assessment. Aneurysmal bone cysts (ABC) are benign expansile osteoclastic giant cell-rich bony neoplasms, composed of numerous blood-filled channels and cystic spaces 1. 18. There was little bleeding. 7. (2008) ISBN:193188403X. ABC accounts for the 'A' in the popular mnemonic for lucent bone lesions FEGNOMASHIC. Giant cystic Schmorl's nodes are unusual entities; their radiologic appearance differs dramatically from the classic description and is diagnostically challenging. VH are the most common spine tumors with an estimated incidence of 1.9-27% in the general population. Pain resolved; paresthesia improved and no recurrence. Modic et al. 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. The tumor has a heterogeneous appearance on both T1 and T2-weighted MR, with focal areas of high T1 signal, presumably representing blood. AJR Am J Roentgenol. Dawson EG, Mirra JM, Yuhl ET, Lasser K. Brodsky AE, Khalil M, VanDeventer L. Matsumoto K, Fujii S, Mochizuki T, Hukuda S. Park CK, Cho KK, Lee SW, Jeon JS, Kang JK, Choi CR. OA can happen from simple wear and tear over time, or because of a sudden injury to a joint . In general, vertebral pneumatocysts are less common than intraosseous pneumatocysts in the pelvis, especially adjacent to the sacroiliac joint. Conclusion: T3 vertebral lytic lesion. Initially, the patient was treated conservatively but the pain did not improve. 2010;10(2):e5-9. Prominent ridges of bone can appear as pseudotrabeculation on x-ray but in fact, UBC is usually unilocular.

Corticosteroid injection had been described for lesion in the peripheral skeleton can be considered when the risk of fracture is low [30, 23]. The patient was suspected of having degenerative disk disease, so she was referred to our radiology department for examination. In some instances, surgery with curettage and bone grafting is required. 43 New Scotland Ave, Albany NY, 12208. Imaging in Oncology.

Iowa Orthop J. The imaging methods included radiography, whole-body bone scintigraphy (WBBS), CT and MRI. 1995;164(3):573-80. Typically vertebral haemangiomas occur in the thoracic spine, specifically within the vertebral body. (Table 1). This condition is characterized by pain in the lower back and buttocks, and sometimes down the back of the legs. imaging (MRI). 4. A: Clinical presentation of spine aneurysmal bone cysts varies depending on the tumor location and involvement of the spinal cord and nerve roots. The term aneurysmal is derived from its radiographic appearance. SBC accounts for the 'S' in the popular mnemonic for lucent bone lesions FEGNOMASHIC. [3] These lesions are usually an incidental finding . (2020) ISBN: 9789283245025 -. MR images show a multiloculated mass of heterogeneous signal intensity that usually has blood products within (7).

CT scan of the thoracic spine reveals an osteolytic bony lesion involving T3 left posterior element and vertebral body, with a soft tissue mass resulting in cord compression. Abbreviations used: ABC = Aneurysmal bone cyst CMF = Chondromyxoid fibroma EG = Eosinophilic Granuloma GCT = Giant cell tumour FD = Fibrous dysplasia HPT = Hyperparathyroidism with Brown tumor NOF = Non Ossifying Fibroma It breaks down the cartilage. MRI usually detects the multiple blood-filled cystic spaces with fluid-fluid levels and septations separating the cysts. These lesions are usually asymptomatic and found incidentally, although pain, swelling and stiffness of the adjacent joint also occur. 12. Discal cysts (also known as a disk cyst or disc cyst) are uncommon lesions of the spine, representing an extrathecal cyst which communicates with the adjacent intervertebral disc through an annular fissure. The molecular criterion is the USP6 gene (at 17p13.2 locus) rearrangement. Radiology Cases of Vertebral Body Anomalies Radiology Cases of Hemivertebra AP image from a selective angiogram injection of the left renal artery shows fusion of the medial aspect of the left kidney, which has crossed the midline, to the medial aspect of the right kidney, causing the right kidney to be displaced laterally. Results of three years follow-up. Department of Radiology of the Medical University of Vienna, Austria and Rijnland hospital in Leiderdorp, the Netherlands In this article we will focus on spinal cord diseases that are characterised by high signal within the cord on T2WI. 2005;25:69-74. 2013;5(3):e43. Abstract The computed tomographic (CT) appearance and the pain radiographic and myelographic findings of vertebral hydatid disease (caused by Echinococcus granulosus) in two patients are presented. [1] Usually benign, this lesion is of vascular origin and like hemangiomas in other parts of the body usually involves a proliferation of normal capillary and venous structures. Until now, to our knowledge, only 10 cases of a simple bone cyst involving the vertebrae have been reported, with four of them in the cervical vertebrae. Any other prior symptoms are mild pain, local tenderness, and swelling (5). 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. CT and MRI add little to the diagnosis, however, can be helpful in eliminating other entities that can potentially mimic a simple bone cyst (see differential diagnosis below) 8. Compared to the other lesions in this list, aneurysmal bone cysts are markedly expansile (hence, "aneurysmal") and have a thin cortical shell. show answer. This article has not yet been cited by articles in journals that are participating in Crossref Cited-by Linking. 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. 14. Broadly, these lesions can be separated into: aneurysmal bone cyst(<2%): neural arch (60%); vertebral body (40%), Brown tumor(an osteoclast reaction in hyperparathyroidism). However they can occur anywhere within the spine and may be isolated to the posterior elements [2], [3]. Vertebral pneumatocysts are gas-filled cavities within the spinal vertebrae. 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. A complementary MRI performed as part of in-hospital management showed an incidental finding of a cystic lesion in the vertebral body of C2 (Figure 1). To the best of our knowledge, 21 cases of SBCs affecting the vertebra have been reported in the English literature.
