Giant cystic Schmorl's nodes are unusual entities; their radiologic appearance differs dramatically from the classic description and is diagnostically challenging. The imaging evaluation includes computed tomography (CT), myelogra-phy and magnetic resonance imaging (MRI). The larger posterior part of the vertebral body is displaced backward into the spinal canal. Typically vertebral haemangiomas occur in the thoracic spine, specifically within the vertebral body. 2002;179 (3): 667-9. Case 1, (A): Axial T2-weighted MR image of twelfth thoracic spine vertebrae; (B): Sagittal T2-weightedimages of thoracic spine vertebrae. There was little bleeding. 3. 5). 2004;25(7):1291-3.

Prominent ridges of bone can appear as pseudotrabeculation on x-ray but in fact, UBC is usually unilocular. The patient underwent surgery and excisional biopsy through the posterior approach. Blumberg M. CT of Iliac Unicameral Bone Cysts. The bone scan was negative. CT could precisely show and localize all niduses, and calcification was always detected. Symptoms. In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. On plain radiography (and to a lesser degree, CT), the differential diagnosis includes most of the lesions included in the mnemonic FEGNOMASHIC. Lesions coming from the cervico-brachial plexus are expected to be found in more paraspinal locations. According to the radiologic findings, the lesion was identified as a simple bone cyst, and the diagnosis was verified by surgical and histopathologic examinations. They shared a spinal cord and had the presence of an open spinal defect type meningocele . He remained free of symptoms in the back and had a high level of sports activity. Adam Greenspan, Gernot Jundt, Wolfgang Remagen. 1 Two types of endplate changes were originally described, with a third type subsequently added in a later publication: 2, 3 Spinal involvement is typically in the posterior elements, although extension into the vertebral body is also common [3]. A case report, Solitary bone cyst of a lumbar vertebra. (2020) ISBN: 9789283245025 -. Expertddx. The lesion can be categorized according to the bone reporting and data system as Bone-RADS 4 unless histology has been already obtained 7. Search Main Page; Pub Med; Search Feeback 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. Vertebral tumors can cause different signs and symptoms, especially as tumors grow. No complications were identified. The cartilaginous layer is related to the nucleus pulposus and annulus fibrosus and has an important role in intervertebral disc nutrition 1. Patients age, history, clinical and laboratory data and radiologic findings can help with the diagnosis [5]. 2015;101(1):S119-27. Aneurysmal bone cysts commonly present with pain and swelling. Abbreviations used: ABC = Aneurysmal bone cyst CMF = Chondromyxoid fibroma EG = Eosinophilic Granuloma Conclusion: Findings are suggestive of an aneurysmal bone cyst. the sacroiliac joint. The vertebra is divided anatomically into the vertebral body anteriorly and the neural arch posteriorly. Cyst removed from a vertebral body Fig. 2005;23(27):6756-62. We intend to report two cases of SBC located in the vertebral body, and review the literature. Musculoskeletal Imaging. The patient underwent surgery to remove the suspected simple bone cyst in the C4 vertebra. In the spine, the most typical site of localization is the sacrum; other vertebral segments are rarely involved (7). (2008) ISBN:193188403X. Reference article, Radiopaedia.org (Accessed on 18 Jan 2023) https://doi.org/10.53347/rID-45139, acute disseminated encephalomyelitis (ADEM), subacute combined degeneration of the cord, occasionally a fluid/fluid or blood/fluid level is seen. Focal areas of high T1 and T2 signal 4 are also seen, presumably representing areas of blood of variable age (see aging blood on MRI). Aneurysmal bone cysts have been first described by the American bone pathologist Louis Lichtenstein in 1950 14. 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. They are more common in males (M:F ~ 2-3:1) 2,6. It is important to remember that the presence of fluid-fluid levels, although characteristic of aneurysmal bone cysts, is by no means pathognomonic, and is seen in other lesions as well, both benign and malignant (e.g. They are classically first imaged by X-ray and subsequently confirmed by CT or MR imaging. X-ray and computed tomography (CT) characterize by expansile osteolytic lesions with thin sclerotic margins and fluid lines. The cyst had a thin wall and was lined by flat epithelial cells with a mesothelial appearance (Fig 6C). Although, SBCs can involve one or multiple parts of the vertebra (body, pedicle, lamina or spinous process), only eight cases of SBC in the vertebral body were reported. Medical Center). During the active phase, the cyst remains adjacent to the growth plate. Neuroradiology Companion. Simple bone cysts are common, benign, fluid-filled, cystic lesions that cause minimal expansion of the bone and usually occur in the metaphysis of long bones. Features on CT are similar to plain radiographs but CT has the advantage of characterizing extent, detecting radiograph-occult fractures, and assessing internal density (usually between 10-15 HU) 8. 2023 by the American Society of Neuroradiology | Print ISSN: 0195-6108 Online ISSN: 1936-959X. 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. Aneurysmal bone cysts are multiloculated, expansile, highly vascular, osteolytic lesions that are filled with free-flowing blood products with fluid levels. Eur Spine J. (Table 1). Check for errors and try again. 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. The reported peak is between 3 and 14 years of age, with the mean age at diagnosis being approximately 9 years. There was no recurrence. 12. Hence, we used all these three imaging techniques to make a complete diagnosis. The cyst will clearly appear as a bubble-like growth near a facet joint, which is a connection between vertebrae of the spine. The end plates (zones of provisional calcification) maintain normal mineralization, and so appear strikingly dense compared to adjacent osteoporotic bone. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Body and right pedicle and transverse process, Copyright 2023 Oxford University Press and JSCR Publishing Ltd. Axial nonenhanced CT scan with bone window of the fourth cervical vertebra. Magnetic resonance imaging demonstrated mixed signal on both T1- and T2-weighted sequences, with cystic and enhancing solid portions. Radiology. AJR Am J Roentgenol. Although there is an overlap in appearances, characteristic imaging features can aid in the distinction between these 2 types of compression fractures. In this article we will discuss the differential diagnosis of well-defined osteolytic bone tumors and tumor-like lesions. The previously termed 'giant lesion of small bones' features the same morphological features as the solid subtype of aneurysmal bone cyst 1. 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. Depending on the type of surgery. The pain can. We describe the imaging findings of an unusual type of Schmorl's node appearing as giant cystlike lesion of the vertebral bodies. Microscopic examination revealed mature fat cells, muscle fibers, and connective tissue fragments of the tendons that showed chondroid metaplastic foci (Fig 6A). The current study aimed to investigate the imaging manifestations of vertebral aneurysmal bone cyst (ABC), and examine the clinical value of interventional embolization. 2.

The diagnosis of FIF was initially made preoperatively by the characteristic findings of imaging studies. They are typically intramedullary and active cysts are found in the metaphysis of long bones, abutting the growth plate 1. 2020;68(4):843. Although now generally considered as part of the vertebral body, historically they had been grouped with the intervertebral disc 3. Gamanagatti S, Ghosh A, Singh A, et al. 2013;5(3):e43. Vertebral tumor signs and symptoms may include: Pain at the site of the tumor due to tumor growth. This rare pathognomic radiologic finding is known as fallen fragment sign (12). ABC accounts for the 'A' in the popular mnemonic for lucent bone lesions FEGNOMASHIC. 2022. 2. Lippincott Williams & Wilkins. The bone scan showed a cold spot at the site of the lesion. 5. They may cause expansion of the bone with thinning of the overlying cortex. SBC accounts for the 'S' in the popular mnemonic for lucent bone lesions FEGNOMASHIC.

A case of a simple bone cyst in the spinous process of the fourth cervical vertebra in a 26-year-old woman is reported. AJR Am J Roentgenol. The patient had no recurrence seven years after surgery. Simple or solitary bone cysts (SBC) also known as unicameral bone cysts are benign lesions commonly seen in the peripheral skeleton [1]. Welcome VIN Logout The etiology and pathogenesis are unknown 8,10. A: The differential diagnosis of aneurysmal bone cysts is giant cell tumor, chondroblastoma, chondromyxoid fibroma, osteoblastoma, eosinophilic granuloma, and telangiectatic osteosarcoma. The radiologic appearance of the lesion of our patient was not multiloculated and did not have fluid-fluid levels, blood degradation products, or soft tissue around the lesion. Computed tomography (CT) showed a multi-lobulated osteolytic lesion within the T12 body with extension to the right pedicle and transverse process (Fig. Diagnostic Radiology: Musculoskeletal and Breast Imaging. 2020;11:274. Other studies described the prevalence of low bone mass in any site, lumbar spine, total body and femoral neck and/or total femur, despite of age below 20 years, and found higher prevalence from 23% to 68% 12 12 Dodd JD, Barry SC, Barry RB, Cawood TJ, McKenna MJ, Gallagher CG.

Aneurysmal Bone Cyst of the Spine in Children. Magnetic resonance imaging (MRI) revealed a well-defined lesion with low signal intensity on T1 and high signal intensity on T2 weighted images (Fig. These benign lesions most frequently affect individuals in the first and second decades of life. Thus patients should be referred to an orthopedic oncologist 7. Michael A. Blake, Mannudeep K. Kalra. Welcome, VIN Public! Dawson et al (3) were the first investigators to describe a simple bone cyst developing in cervical vertebrae, and it was located in the C4 vertebra. However in patients older than 40 years, while dealing with posterior element lesions, metastasis must always be kept in mind. Posterior spinal fusion was performed with instrumentation with pedicle screws from T10 to L2 and a mixture of autologous bone graft and allograft was used to achieve better fusion (Fig. This case illustrates the radiological findings of an aneurysmal bone cyst with the typical MRI fluid-fluid levels and septations separating the cysts.

Aneurysmal bone cyst: A pathologic entity commonly mistaken for giant cell tumour and occasionally for hemangioma and osteogenic sarcoma. Aneurysmal bone cysts are rare. 70% of patients have neurologic deficit. 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. 1. elementary radiological lesions include angular lesions of the vertebral body, non-specific spondylodiscitis (very similar to infectious forms), osteolytic lesions with varying degrees of collapse of the vertebral body (visible lesions even in childhood), osteosclerosis of one or more vertebral bodies with development of hyperostosis, Both genders are equally affected 1.

In general, vertebral pneumatocysts are less common than intraosseous pneumatocysts in the pelvis, especially adjacent to the sacroiliac joint. 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. The definitive diagnosis of aneurysmal bone cysts is based on a combination of typical radiological and pathological features. 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. J Am Acad Orthop Surg. 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. MAIN: : Radiology of the Spine. A 26-year-old male presented with pain over the lower lumbar area. Soft Tissue and Bone Tumours. Aneurysmal bone cyst. MR imaging shows an expansile mass involving the T3 left-sided posterior arch and vertebral body, destroying the lamina and pedicle with epidural extension. Roentgenography usually shows simple bone cysts as well-defined, intramedullary, metaphyseal, and pure lytic lesions. Check for errors and try again. A: Aneurysmal bone cysts may be associated with other tumors like chondroblastoma, chondromyxoid fibroma, fibrous dysplasia, and giant cell tumor. The imaging characteristics are otherwise non-specific. Methods: An 86-year-old woman was referred to our spine service for a 2-year history of anterior thigh and leg pain. 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). If large and threatening to fracture, or causing deformity then an intralesional steroid injection can be performed 3-5. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. Rare Tumors. The lateral view of radiographs of the cervical vertebrae demonstrated a faintly visible osteolytic lesion causing minimum expansion in the C4 vertebral spinous process (Fig 1). Current Diagnosis & Treatment in Orthopedics. UBCs are usually found in children in the 1st and 2nd decades (65% in teenagers) with the mean age at diagnosis being 9 years 8. 2010;19 (10): 1621-6. spinal infection / inflammation / degeneration. Summary: Simple bone cysts are common, benign, fluid-filled, cystic lesions that occur mostly in the metaphysis of the long bones and are rarely found in vertebrae.
