vertebral body cyst radiology

occupying most of the height of the L2 vertebral body (Figure 2). A case report, Unicameral bone cyst of a lumbar vertebra. Internal signal heterogeneity, periosteal reaction and soft tissue edema can be seen in the setting of fracture 8. 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. The only symptom reported by the patient was cervical pain irradiated to shoulders. Local recurrence rates are ~15% (range 10-20%) 10. 9. Diagnostic Neuroradiology. They are usually found in young adults 1,2. In the table the most common sclerotic bone tumors and tumor-like lesions in different age-groups are presented. 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). During the active phase, the cyst remains adjacent to the growth plate. Those cysts predominantly occur in male patients with a ratio of 2.5:1. especially posterior elements of the spine with extension into the vertebral body in 40% of cases 5. obturator foramen in . Steven P. Meyers. 4). The rising bubble sign is considered pathognomonic and occurs when a gas bubble is seen at the most non-dependent part of the UBC 8,10. In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. 1. 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. 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 . 2010;10(2):e5-9. The recurrence rate of 15-30% has been described 3. They are most common at cervical levels. Fig. AJR Am J Roentgenol. Study design: Case report. Breakage of a cyst can trigger an immunological reaction from the host, sometimes leading to an anaphylactic shock. Musculoskeletal Imaging. ADVERTISEMENT: Supporters see fewer/no ads. Cervical MR images showed a unilocular homogeneous cyst having regular contours and measuring 10 8 mm in the spinous process of C4 vertebra (Fig 3). The stroma corresponds to septations with fibroblasts, spindle cells, osteoids, and numerous benign giant cells. 4. They may cause expansion of the bone with thinning of the overlying cortex. Michael A. Blake, Mannudeep K. Kalra. The reported cases were more common in women (n=13, 61.9%) than men (n=8, 38.1%). In support of this theory is the fact that they are primarily encountered in young men, and are often hemorrhagic at surgery 1. A growing body of research supports the above study [Lee S.W. A follow-up MRI performed after the delivery showed a well-defined mass with the cystic formation in the left abdominal region with a centrally located fetiform structure. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Neto A, Vertebral aneurysmal bone cyst. show answer. 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. Although there is an overlap in appearances, characteristic imaging features can aid in the distinction between these 2 types of compression fractures. On rare occasions, this is the result of a pathologic fracture. Notice that many benign osteolytic lesions that are . Axial nonenhanced CT scan with bone window of the fourth cervical vertebra. Reference article, Radiopaedia.org (Accessed on 18 Jan 2023) https://doi.org/10.53347/rID-7189, {"containerId":"expandableQuestionsContainer","displayRelatedArticles":true,"displayNextQuestion":true,"displaySkipQuestion":true,"articleId":7189,"questionManager":null,"mcqUrl":"https://radiopaedia.org/articles/unicameral-bone-cyst-1/questions/2234?lang=us"}. 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. Surgery shows promising outcomes in large SBCs in the vertebral body with a high risk of fracture. 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 Radiographic features Plain radiograph Difficult to detect, but sometimes gas lucencies are seen within the vertebral bodies. A, Chondroid metaplastic foci in the connective tissue surrounding the lesion (hematoxylin-eosin stain 100). Simple or solitary bone cysts (SBC) also known as unicameral bone cysts are benign lesions commonly seen in the peripheral skeleton [1]. To our knowledge, only four were in cervical vertebrae (36), and the rest were in lumbar vertebrae (2, 4). Differential Diagnosis in Orthopaedic Oncology. show answer. Search for other works by this author on: University of Shahid Beheshti Medical Sciences. Uncommon Manifestations of Intervertebral Disk Pathologic Conditions. The pain can. 2. 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. I suggest as others have that Cerebellar tonsillar ectopia as being trauma-induced and Arnorld Chiari 1 malformation to be congenital, though some would disagree. The differential diagnosis depends on the modality. J Am Acad Orthop Surg. 8. The diagnosis of FIF was initially made preoperatively by the characteristic findings of imaging studies. Vertebral endplate changes were redefined with the advent of MRI, which enabled visualization of previously unrecognized alterations in marrow signal. 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). Vertebral body endplates are anatomically-discrete structures that form the interface between the vertebral bodies and the adjacent intervertebral discs. Lesions coming from the cervico-brachial plexus are expected to be found in more paraspinal locations. AJR Am J Roentgenol. It may be asymptomatic, and hence the incidence is unknown. Topouchian V, Mazda K, Hamze B, Laredo J, Penneot G. Aneurysmal Bone Cysts in Children: Complications of Fibrosing Agent Injection. Abbreviations used: ABC = Aneurysmal bone cyst CMF = Chondromyxoid fibroma EG = Eosinophilic Granuloma There is a minimally expansile lesion of the spinous process of C4 vertebra (arrow). solitary lucent bone lesion, high T1 or low T1 bone lesion, location within the bone (eccentric, central). In conclusion, this study presents two cases of SBCs and reviews the literature. 2020;11:274. 4. The specimen was sent for pathologic examination. The end plates (zones of provisional calcification) maintain normal mineralization, and so appear strikingly dense compared to adjacent osteoporotic bone. Modic et al. We describe the imaging findings of an unusual type of Schmorl's node appearing as giant cystlike lesion of the vertebral bodies. Skeletal Radiol. A case of a simple bone cyst in the spinous process of the fourth cervical vertebra in a 26-year-old woman is reported. If there is a fracture through this lesion a dependent bony fragment may be seen, and this is known as the fallen fragment sign. Often, however, they expand secondarily into the pedicles and vertebral body (7). The neural arch is composed of bilateral pedicles, pars interarticularis, and laminae; from the neural arch arise the spinous process, bilateral transverse processes, and bilateral superior and inferior articulating processes. Vertebral Lesions: Imaging Algorithm 1 Algorithm 2 Initial imaging usually consists of plain radiography. A large clear fluid-filled cavity was curetted and the cavity was filled with an autologous bone graft from iliac crest. 70% of patients have neurologic deficit. Locations include 1,2,5: occurrence elsewhere is relatively uncommon, and usually occurs in adults. Nayman A, Guler I, Erdogan H, Koplay M. Funayama T, Gasbarrini A, Ghermandi R, Girolami M, Boriani S. Boude AB, Vsquez LG, Alvarado-Gomez F, Bedoya MC, Rodrguez-Mnera A, MoralesSaenz LC. Soft Tissue and Bone Tumours. Conclusion: T3 vertebral lytic lesion. 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. In our cases, due to benign course of disease and imaging that suggested a benign lesion, we decided to do an open biopsy and definite surgery at the same time. 15. Here an illustration of the most common sclerotic bone tumors. Primary bone tumors. When aneurysmal bone cysts are found in vertebrae, they typically occur in the posterior elements, including the transverse process, spinous process, lamina, and neural arches. Iowa Orthop J. Fourney DR, Frangou EM, Ryken TC, Dipaola CP, Shaffrey CI, Berven SH, et al. Dawson EG, Mirra JM, Yuhl ET, Lasser K. Brodsky AE, Khalil M, VanDeventer L. Matsumoto K, Fujii S, Mochizuki T, Hukuda S.

A single vertebral surgical approach for spinal extradural meningeal cysts spanning multiple vertebral segments by auxiliary neuroendoscope. 21 this benign vascular tumor of the vertebral body, often discovered incidentally on imaging, can be associated with vertebral body collapse and epidural extension with spinal cord compression; on rare occasions, it may exhibit aggressive growth. They are mostly seen in children and adolescents, with ~80% under the age of 20 years 2,3but can occur at any age 1. Neuroradiology Companion. We intend to report two cases of SBC located in the vertebral body, and review the literature. Kumar B, Thirumal R, Chander S. Aneurysmal Bone Cyst of Thoracic Spine with Neurological Deficit and Its Recurrence Treated with Multimodal Intervention A Case Report. Active unicameral bone cysts occur most frequently between the ages of 1 and 10 years. This may be the reason why simple bone cysts occur in vertebrae in an older age group than do the cysts of long bone. Lovell and Winter's Pediatric Orthopaedics. 3. Our case reports the fifth simple bone cyst developing in cervical vertebrae. Vertebral metastasesare significantly more common than primary bone tumors, especially in an older patient or one with known primary disease elsewhere. They are classically first imaged by X-ray and subsequently confirmed by CT or MR imaging. 3. Axial postcontrast T1-weighted MR image demonstrates similar signal intensity characteristics as those of precontrast T1-weighted images (not shown) that define nonenhancing lesions. The bone scan showed a cold spot at the site of the lesion. 2022. Symptoms. SBCs were found in cervical (n=10, 47.6%), lumbar (n=10, 47.6%) and thoracic (n=1, 4.8%) regions. 2004;24 (8): 1707-10. Assessment of whether the bone lesions are sclerotic or lytic may help to narrow the differential diagnosis of primary disease if it is unknown. 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. The biology behind the human intervertebral disc and its endplates. Reference article, Radiopaedia.org (Accessed on 18 Jan 2023) https://doi.org/10.53347/rID-70932. Unicameral bone cysts were initially described by the German pathologist Rudolf Virchow in 1891 8,9. The following molecular criterion is desirable: USP6 gene (at 17p13.2 locus) rearrangement; occurs in 63% of cases. 5. The thecal sac was partially encased, compressed and deviated to the right side. 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. Lichtenstein L. Aneurysmal bone cyst: A pathologic entity commonly mistaken for giant cell tumour and occasionally for hemangioma and osteogenic sarcoma. 2 VHs are more frequently found in women, especially in the fourth-to-sixth decades of life. 2004;25(7):1291-3. 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]. A: Aneurysmal bone cysts are benign osteolytic lesions comprised of blood-filled channels separated by multiple connective septations containing osteoid tissue and osteoclast giant cells. We do not capture any email address. Diagnostic Radiology: Musculoskeletal and Breast Imaging. The imaging methods included radiography, whole-body bone scintigraphy (WBBS), CT and MRI. , who described a fetus in fetu with spinal .

Differential diagnosis of the spinal lesion can be narrowed by patients age, history, laboratory test, imaging studies and location of the tumor. Hence, spinal SBC should be considered in the differential diagnosis of spinal lesions. Gamanagatti S, Ghosh A, Singh A, et al. Compared to the other lesions in this list, aneurysmal bone cysts are markedly expansile (hence, "aneurysmal") and have a thin cortical shell. The term aneurysmal is derived from its radiographic appearance. Rapp T, Ward J, Alaia M. Aneurysmal Bone Cyst.

Ann Med Surg (Lond). (2006) Proceedings (Baylor University. 2. A case of a simple bone cyst in the spinous process of the fourth cervical vertebra in a 26-year-old woman is reported. The main differential includes both lesions with intrinsic fluid-fluid levels (see fluid-fluid level containing bone lesions) and those from which an aneurysmal bone cyst may arise: osteosarcoma: especially telangiectatic osteosarcoma. Vertebral hemangiomas (VHs) are the most common benign tumors of the spine. Veena Chowdhury, Arun Kumar Gupta, Niranjan Khandelwal. Additionally, CT can demonstrate fluid-fluid levels, which are harder to appreciate than on MRI and require viewing with a narrow window width 8. show answer. essential: simple cyst lacking a true lining with typical imaging features, desirable: fibrin-like deposits +/- mineralization forming cementum-like structures. Vertebral pneumatocysts: uncommon lesions with pathognomonic imaging characteristics. Another suggestion is that venous obstruction of interstitial fluid drainage might be the cause (10).

The patient underwent surgery to remove the suspected simple bone cyst in the C4 vertebra. Harry B. Skinner. 2. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Giant cell tumors of the spine only accounts for 37% of primary bone tumors. 2014: 545017. The vertebra is divided anatomically into the vertebral body anteriorly and the neural arch posteriorly. ABC accounts for the 'A' in the popular mnemonic for lucent bone lesions FEGNOMASHIC. 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. MRI of Bone and Soft Tissue Tumors and Tumorlike Lesions. Histologically, ABC is typically characterised by blood-filled cystic spaces separated by a spindle cell stroma with osteoclast-like giant cells and osteoid or bone production. Thieme Medical Pub. 22 mri sequences of the typical (fatty) Current Diagnosis & Treatment in Orthopedics. They are typically eccentrically located in the metaphysis of long bones 1, adjacent to an unfused growth plate. The vertebral body and vertebral vessels are not involved. The pathogenesis of simple bone cysts is still unknown. In addition, predominantly mature compact bone and focal spongious bone fragments containing bone marrow elements were seen (Fig 6B). 6. Case study, Radiopaedia.org (Accessed on 18 Jan 2023) https://doi.org/10.53347/rID-149389, Real Hospital Portugus de Pernambuco - Recife, PE - Brazil. The sensitivity to specify a vertebral lesion on an X-ray is difficult as well. The molecular criterion is the USP6 gene (at 17p13.2 locus) rearrangement. It might show concerning features such as cortical breach or soft tissue extension 7,8. Hammoud S, Weber K, McCarthy E. Unicameral Bone Cysts of the Pelvis: A Study of 16 Cases. The spinous process and the lesion within were removed. Prominent ridges of bone can appear as pseudotrabeculation on x-ray but in fact, UBC is usually unilocular. Thank you for your interest in spreading the word on American Journal of Neuroradiology. A: Histological features of aneurysmal bone cysts usually show blood-filled spaces without endothelial lining between fibrous stromata.
