AJR Am J Roentgenol. Vertebral pneumatocyst. AJNR Am J Neuroradiol. In this article we will discuss a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions. The differential diagnosis depends on the modality. Check for errors and try again. Vertebral endplate changes were redefined with the advent of MRI, which enabled visualization of previously unrecognized alterations in marrow signal. There is a minimally expansile lesion of the spinous process of C4 vertebra (arrow). In conclusion, this study presents two cases of SBCs and reviews the literature. A 24-year-old male presented with acute low back pain with no prior traumatic events. Plain radiographs are the first-line imaging modality. There was little bleeding. A large clear fluid-filled cavity was curetted and the cavity was filled with an autologous bone graft from iliac crest. They are constituted peripherally by an epiphyseal bone ring and centrally by a cartilaginous layer. Check for errors and try again. The mass compresses the cord, pushing it forward and to the right. Spinal SBC, especially in the vertebral body, is not a common lesion and there is limited data regarding managing these lesions [626]. The spinous process and the lesion within were removed. ABC accounts for the 'A' in the popular mnemonic for lucent bone lesions FEGNOMASHIC. ADVERTISEMENT: Supporters see fewer/no ads.

Vertebral hemangiomas are an incidental and relatively common radiological finding and a benign tumor of vascular origin. An aneurysmal bone cyst is an expansile osteolytic lesion with a thin wall, containing blood-filled cystic cavities. Speak With Our Team. Compared to the other lesions in this list, aneurysmal bone cysts are markedly expansile (hence, "aneurysmal") and have a thin cortical shell. 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. Aydin S, Abuzayed B, Yildirim H et-al. Breakage of a cyst can trigger an immunological reaction from the host, sometimes leading to an anaphylactic shock. Patients age, history, clinical and laboratory data and radiologic findings can help with the diagnosis [5]. However they can occur anywhere within the spine and may be isolated to the posterior elements [2], [3]. Our goal was to present two cases of SBC who were referred to our department of spine surgery and review the literature. Haaga, John R. 1945-. Knowing the cyst's size and position will help the doctor develop a treatment plan. especially posterior elements of the spine with extension into the vertebral body in 40% of cases 5. obturator foramen in . Giant cell tumors of the spine only accounts for 37% of primary bone tumors. Lippincott Williams & Wilkins. 2015;101(1):S119-27.

Surgery shows promising outcomes in large SBCs in the vertebral body with a high risk of fracture. Unable to process the form. 6. The imaging methods included radiography, whole-body bone scintigraphy (WBBS), CT and MRI. 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. Imaging technology precisely guides minimally invasive procedures with needles, catheters and other devices. Q: How are spine aneurysmal bone cysts diagnosed? CONCLUSION. Solid variant ABC of long tubular bones: A diagnostic conundrum for the radiologist. Methods: An 86-year-old woman was referred to our spine service for a 2-year history of anterior thigh and leg pain. Spinal Cyst Treatment Conservative treatment may include rest, anti-inflammatory medications, painkillers, steroid injections and drainage. Broadly, these lesions can be separated into: aneurysmal bone cyst(<2%): neural arch (60%); vertebral body (40%), Brown tumor(an osteoclast reaction in hyperparathyroidism). J Am Acad Orthop Surg. Needle biopsies may be a problem because the material may consist of mostly blood elements. Bone cysts have previously been considered a minor diagnostic criterion [2], but they are no . The cysts are of a variable signal, with a surrounding rim of low T1 and T2 signals. This paper describes a fourth case of vertebral sarcoidosis and emphasizes the radiographic features of the disease. Front Page; Message Boards; Search.

Coskun B, Akpek S, Dogulu F, Uluoglu O, Eken G. Simple Bone Cyst in Spinous Process of the C4 Vertebra. Figure 7-3 Sacral Aneurysmal Bone Cyst. The differential diagnosis of an expansile cystic lesion involving the posterior elements of vertebrae, such as spinous processes in children or young adults, should include aneurysmal bone cyst, giant cell tumor, and simple bone cyst (5). We discuss the radiologic differential diagnosis of simple vertebral bone cysts, and the surgical and histopathologic verifications of the diagnosis are presented. 3. On opening, a lesion containing fluid involving the spinous process was seen. Steven P. Meyers. CT and MR imaging were also used to determine the extent of the lesions and detect possible complications such as fractures. Some of them are found in diaphysis. Roentgenography usually shows simple bone cysts as well-defined, intramedullary, metaphyseal, and pure lytic lesions. Unable to process the form. Gas measures about -580 to -1000 HU in density 3. The stroma corresponds to septations with fibroblasts, spindle cells, osteoids, and numerous benign giant cells. The bone scan showed a cold spot at the site of the lesion. The differential diagnosis for a vertebral body massis broad and may range from a completely benign bone island to a malignant primary bone tumor.

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. They are classically first imaged by X-ray and subsequently confirmed by CT or MR imaging. 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. During the active phase, the cyst remains adjacent to the growth plate. Unicameral bone cysts are well defined geographic lucent lesionswith a narrow zone of transition,mostly seen in skeletally immature patients, which are centrally located and show a thin sclerotic margin in the majority of cases with no periosteal reactionor soft tissue component. Aneurysmal bone cysts have been first described by the American bone pathologist Louis Lichtenstein in 1950 14. 4.196 Osteoporosis in a 13-year-old girl due to long-term steroid therapy for renal disease with simultaneously decreased body height and codfish vertebral shape.
