High signal on noncontrast T1WIs is most often due to fat. Surgery shows promising outcomes in large SBCs in the vertebral body with a high risk of fracture. Every spine lesion should be approached carefully and pathologic confirmation is prudent. 3, pp. 5). 5, Workup of bone lesion: Lytic vs. sclerotic; evaluates matrix and best defines anatomy of bony involvement, Pros: Chest, abdomen and pelvic CT scan simultaneously screens for primary cancer; superior to skeletal survey in multiple myeloma (MM); > 885 HU (mean), 1,060 HU (maximum) compatible with bone island rather than osteoblastic metastatic disease 11, Cons: Cortical destruction usually needed for detection; poor sensitivity for lesions that infiltrate bone marrow without cortical involvement, Workup of bone lesion: Fat within lesion implies benignity; low signal on T1WI and T2WI suggests sclerotic lesion; halo of high signal on T2WIs on MRI around a lesion that has been shown to be sclerotic on CT suggests osteoblastic metastatic disease as opposed to bone island 5. 5, pp. E. Mascard, A. Gomez-Brouchet, and K. Lambot, Bone cysts: Unicameral and aneurysmal bone cyst, Orthopaedics & Traumatology: Surgery & Research, vol. 19, no. 2005;26(1):30-3.

They have been traditionally treated operatively with intralesional curettage or excision or complete en bloc excision with bone grafting are options 3. Q: What is the differential diagnosis of aneurysmal bone cysts? 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. Studies concluded it was a tumoral lesion with benign characteristics. There is still no agreement regarding the best therapeutic approach [7, 9, 11]. 27.1). (d) MRI of the lesion. 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). Aneurismal cysts are osteolytic multiloculated lesions, filled with fluid, predominant in women in the third decade of life and affect long bone metaphysis.

show answer. With increased utilization of spine MRI, it is expected that incidental bone lesions will be frequently detected. The greater the amount of fat, the more indolent the lesion, the higher the signal on T1WI and the more complete the suppression of signal on fat-suppressed images. Initially, the patient was treated conservatively but the pain did not improve. Correspondence address. The histopathology showed a pattern compatible with an aneurysmal bone cyst. Lippincott Williams & Wilkins. S119S127, 2015. Posterior elements: Lesions arising in the posterior elements are more likely to be primary bone tumors. Our goal was to present two cases of SBC who were referred to our department of spine surgery and review the literature.

A complete blood count, urinalysis, basic serum chemistries, as well as serum-free light chains, serum, and urine protein electrophoresis to evaluate for the possibility of multiple myeloma should be performed. Curtis A. Dickman, Michael Fehlings, Ziya L. Gokaslan. ADVERTISEMENT: Supporters see fewer/no ads. Vertebral metastasesare significantly more common than primary bone tumors, especially in an older patient or one with known primary disease elsewhere. Among primary bone tumors, solitary bone cysts are infrequent lesions that occur mostly in males with a ratio of 2.5:1 [4]. This is an open access article distributed under the. Vertebral lesion (differential). At the time the article was last revised Mostafa El-Feky had no recorded disclosures. 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. 7. 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. 6, no. Signal suppresses completely on fat-suppressed sequences. Complementary studies suggested the benign nature of the lesion. show answer. Interventional Radiology). Lichtenstein L. Aneurysmal bone cyst: A pathologic entity commonly mistaken for giant cell tumour and occasionally for hemangioma and osteogenic sarcoma. 260272, 2014. 3. It is therefore important to differentiate benign lesions, which need no treatment or follow-up, from those that will require additional evaluation and possibly affect patient management. Aneurysmal bone cyst. A 26-year-old male presented with pain over the lower lumbar area. The tumor has a heterogeneous appearance on both T1 and T2-weighted MR, with focal areas of high T1 signal, presumably representing blood. A. J. Fenoy, J. D. W. Greenlee, A. H. Menezes et al., Primary bone tumors of the spine in children, Journal of Neurosurgery, vol. 9 , 10, Gadolinium contrast enhancement may also be helpful as although red marrow enhances to a greater extent than yellow marrow, marked enhancement is atypical. Conclusions. View Frank Gaillard's current disclosures, see full revision history and disclosures, acute disseminated encephalomyelitis (ADEM), subacute combined degeneration of the cord, occasionally a fluid/fluid or blood/fluid level is seen. II. Secondary Aneurysmal Bone Cyst Following Chondroblastoma of the Patella. No discrete lesion is typically seen on CT. X-ray and computed tomography (CT) characterize by expansile osteolytic lesions with thin sclerotic margins and fluid lines. 25, no. Reference article, Radiopaedia.org (Accessed on 03 Jun 2023) https://doi.org/10.53347/rID-34279. 95, no. The bone scan showed a cold spot at the site of the lesion. The most common differential diagnoses for SBC are aneurysmal bone cyst, brown tumor (hyperparathyroidism), infection and less commonly giant cell tumor. Unable to process the form. At the time the article was created Frank Gaillard had no recorded disclosures. Epidural steroid / local anesthetic may be useful temporising measures. It might show concerning features such as cortical breach or soft tissue extension 7,8. In conclusion, this study presents two cases of SBCs and reviews the literature. Linear areas of decreased signal often seen on the T2WI correspond to coarsened trabeculae. Ganglion and synovial cysts are benign lumps caused by a buildup of fluid in a tendon sheath or joint capsule. 11.

If fractured the bone usually heals normally 5. Complete signal suppression is found on fat-suppressed sequences. reported simple bone cyst cases managed by surgical curettage and use of bone graft without recurrence [9]. A total of 120 subjects, 68 females (aged 20-64 years) and 52 males . show answer. 2013;5(3):e43. Prominent ridges of bone can appear as pseudotrabeculation on x-ray but in fact, UBC is usually unilocular. 9. The lesion can be categorized according to the bone reporting and data system as Bone-RADS 4 unless histology has been already obtained 7. {"url":"/signup-modal-props.json?lang=us"}, Niknejad M, Ashraf A, Knipe H, et al. SBC is a rare benign lesion in the spine and it should be considered in the differential diagnosis when suggested by radiologic investigations. In support of this theory is the fact that they are primarily encountered in young men, and are often hemorrhagic at surgery 1. Extensive enhancement of end plates, disk space, and especially the paravertebral soft tissues may occur in advanced degenerative change but is worrisome for infection so that clinical correlation and laboratory testing for infection, erythrocyte sedimentation rate (ESR), and C-reactive protein is indicated. Vertebral body mass. 2002;179 (3): 667-9. Imaging differential considerations include 1: Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. The differential diagnosis depends on the modality. Body and right pedicle and transverse process, Copyright 2023 Oxford University Press and JSCR Publishing Ltd. They most commonly show up on the top of the wrist, but may also affect the feet or the spine. Cervical curettage followed by tumor excision was performed. 1. Considered the best method of diagnosis. Note degenerative pattern of adjacent intervertebral disks. Currently, FDG-PET/CT is the staging test of choice for lung cancer. If the lesion is indeterminate on MR and CT/plain radiographs, there is no demonstrable primary malignancy and evidence of wider spread metastatic disease, UPEP/SPEP and serum-free light chain assay are negative, and there is no increased uptake on FDG-PET/CT (routine bone scan/SPECT if PET not available), then the indeterminate, solitary lesion may be managed conservatively with close follow-up imaging or a biospy ordered depending on the level of concern of the referring physician and patient. Harry B. Skinner. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Pediatr Radiol. 16 However, these techniques have not replaced the plain radiograph skeletal survey in many tertiary cancer centers and are more expensive and time-consuming. 1991;21(2):114-6. Spinal tumors represent about the 28% of all skeletal muscle tumors in children and most of them are benign. The only symptom reported by the patient was cervical pain irradiated to shoulders. Lesion has lower intensity wall. MRI usually detects the multiple blood-filled cystic spaces with fluid-fluid levels and septations separating the cysts. Q: What is the definition of aneurysmal bone cysts? SBC is a rare benign lesion in the spine and it should be considered in the differential diagnosis when suggested by radiologic investigations. Haithcock JA, Layton KF, Opatowsky MJ. They sometimes expand the bone with thinning of the endosteum without any breach of the cortex unless there is a pathologic fracture. Subchondral region of the femoral heads is most often affected and may be seen on scout images of lumbar spine MRI. (2006) ISBN: 9780781753586 -, 5.

The patient underwent surgery and excisional biopsy through the posterior approach. However, a pathological fracture would cause an increased radioisotope activity.
Plain radiographs are the first-line imaging modality. Hammoud S, Weber K, McCarthy E. Unicameral Bone Cysts of the Pelvis: A Study of 16 Cases. Depending on the type of surgery. Continuity with a severely degenerative disk and irregular vertebral end plates: Degenerative end plate changes have been characterized into three types based on MRI appearance that relates to their chronicity by Modic et al 13 : Modic type I is consistent with more acute edematous change and is T1 signal hypointense and T2 signal hyperintense. At the time the case was submitted for publication Antonio Rodrigues de Aguiar Neto had no recorded disclosures. Conservative treatment may include rest, anti-inflammatory medications, painkillers, steroid injections and drainage. CT scan. Epidural extension may also be detected. Linear areas of decreased signal are seen within the lesion on the T2WI. For many years, skeletal survey plain radiographs have been part of the standard workup in patients suspected of having multiple myeloma. Intervention is usually not required for an asymptomatic lesion. 13, no. This case illustrates the radiological findings of an aneurysmal bone cyst with the typical MRI fluid-fluid levels and septations separating the cysts. This is referred to as the doughnut signwhich results in increased uptake peripherally and a photopenic center. Both lesions were found to be SBC and confirmed by pathology.

Aneurysmal Bone Cyst of Thoracic Spine with Neurological Deficit and Its Recurrence Treated with Multimodal Intervention A Case Report. The stability of the defect was ensured by filling it with bone allograft and by prescribing a postsurgical plastic cervical collar to maintain neck immobilization. The Myeloma working group recommended that patients with smoldering or asymptomatic myeloma undergo WB-MRI (or spine and pelvic MRI if WB-MRI is not available) and that the finding of more than one focal lesion of a diameter greater than 5 mm is definitional for symptomatic disease that requires therapy. Therese J Bocklage, Robert Quinn, Berndt Schmit et al. Physical examination was unremarkable except for tenderness over the lower thoracic spine. Considered excellent test for metastatic prostate cancer. Unable to process the form. Magnetic resonance imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body. Zenmyo M, Komiya S, Hamada T, Inoue A.

Surgery may be recommended for persistent cysts that cause pain and impaired movement. Her physical examination was normal. The patient reports progressive thoracic pain, loss of strength at the T4 sensory level, gradual deterioration of neurological status with lower limb paralysis, and loss of sphincter control. Fisher CG, DiPaola CP, Ryken TC, Bilsky MH, Shaffrey CI, Berven SH, et al. The most frequent presentation is due to pathological fracture1,2,6. Rarely, they are truly multiloculated, which can occur after repeated fractures 3,10. The patient remained with a CTLSO immobilization for 4 months. The cyst will clearly appear as a bubble-like growth near a facet joint, which is a connection between vertebrae of the spine. Both genders are equally affected 1. {"url":"/signup-modal-props.json?lang=us"}, Neto A, Vertebral aneurysmal bone cyst.

The detection of multiple bone lesions on MRI, in combination with clinical data, most commonly leads to the diagnosis of metastatic disease or multiple myeloma. For rare, primary bone tumors, analysis for presence and type of tumor matrix is very important: Osteoid matrix is cloudlike and may be seen in osteoid osteomas, osteoblastomas, and osteosarcomas. The pathology report was consistent with SBC. Case Presentation. The cause of solitary bone cysts is still unknown; some authors have proposed a posttraumatic or posthemorrhagic etiology which could explain the vertebral location especially among the elderly. Incidental finding of typical giant cystic Schmorl's node occupying total height of L4 vertebral body. 252260, 2006. They are frequently lower in signal on T2WI than most other tumors in the differential diagnosis, (plasmacytoma, chordoma and metastatic disease) due to the presence of hemosiderin and fibrous tissue. They are mostly seen in children and adolescents, with ~80% under the age of 20 years 2,3but can occur at any age 1. On MRI, the differential is much shorter, especially when age, location and plain film appearance are taken into account. AJNR Am J Neuroradiol. AJNR Am J Neuroradiol. Both chordomas and BNCTs occur in the vertebral body. Written consent by the mother of the patient and the patient was signed before writing this case report. Iowa Orthop J. Diagnostic Radiology: Musculoskeletal and Breast Imaging. Although they have been described in most bones, the most common locations are 3-5: typically eccentrically located in the metaphysis, especially femur, proximal tibia and fibula, and humerus, especially posterior elements of the spine with extension into the vertebral body in 40% of cases 5, short bones of hands and feet: more often with a central location, craniofacial: jaw, basisphenoid, and paranasal sinuses, epiphysis, epiphyseal equivalent,or apophysis: rare but important. At 612-month follow-up the patient presented no recurrence or symptomatology. {"url":"/signup-modal-props.json?lang=us"}, Gaillard F, Hacking C, El-Feky M, et al. In some instances, surgery with curettage and bone grafting is required. It is important to realize that the majority of the spine and the entire nonaxial skeleton will not be visualized on a routine lumbar spine MR. 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. 18. Such tumors can affect the spine, particularly the posterior elements. Pros: Best screen for metastatic disease to the spine; highest sensitivity for marrow infiltration; also defines extraosseous spread of disease. There are several surgical approaches to removing a cyst and preventing recurrence. Pathological marrow enhances much more quickly, reaches a higher absolute level, and shows significant contrast washout. The patient underwent surgical resection of the tumor. Pros: Best screen for lung cancer, melanoma, and MM. B. E. Snell, A. Adesina, and C. E.

Only a limited number of cases have been found in the cervical spine [7]. 4, pp. Although not completely understood, some authors believe a vertebral pneumatocyst is an extension of intradiscal gas (vacuum phenomenon) 1. This study presents two cases of spinal SBC managed surgically with no recurrence in long-term follow-up. (2008) ISBN:193188403X. 1, pp. Q: What is the treatment for aneurysmal bone cysts? Assessment of whether the bone lesions are sclerotic or lytic may help to narrow the differential diagnosis of primary disease if it is unknown. Majority of cases in the literature were treated surgically, including resection and curettage with or without bone grafting, and no recurrence has been reported (Table 1). Classification Broadly, these lesions can be separated into: non-neoplastic lesions primary bone tumors secondary metastatic disease Non-neoplastic lesions aneurysmal bone cyst (<2%): neural arch (60%); vertebral body (40%) Brown tumor (an osteoclast reaction in hyperparathyroidism) bone island vertebral hemangioma Primary bone tumors
Discrete lesion may be seen on CT with characteristic corduroy pattern. Workup of bone lesion: If sclerotic lesion is cold, probability of osteoblastic metastatic disease is low. The previously termed 'giant lesion of small bones' features the same morphological features as the solid subtype of aneurysmal bone cyst 1. 3. Q: Which are the conditions associated with aneurysmal bone cysts? Results of three years follow-up. In our case this pattern was not evidenced in the MRI. at last follow-up male was well. Because of the elevated risk of fracture and collapse of the vertebra due to the thinning of the cortical the optimal treatment considered was surgical resection of the tumor to prevent further neurological lesions. The etiology and pathogenesis are unknown 8,10. In this case, the proximity of the cyst to the right vertebral artery and the risk of injury was high; however the surgical approach used was successful and no recurrence or instability was evidenced on postoperative MRI. Kitagawa T, Fujiwara A, Tamai K et-al. Aneurysmal bone cysts display cytogenetic rearrangements of the USP6 gene. The case was discussed at the neurosurgery, spine surgery, and neuroradiology service meeting and extension studies such as angiotomography of carotid arteries and vertebrobasilar system and bone scintigraphy were requested to determine the etiology of the lesion because the management and prognosis vary according to the type of tumor. Computed tomography (CT) showed a multi-lobulated osteolytic lesion within the T12 body with extension to the right pedicle and transverse process (Fig. (2006) ISBN: 9781588902221 -, 2. Cancer. Percutaneous treatment with fibrosing agents has also been performed, either in isolation or as a precursor to surgical excision 3,11,12. The following molecular criterion is desirable: USP6 gene (at 17p13.2 locus) rearrangement; occurs in 63% of cases. Aneurysmal bone cysts are poorly vascular 10. (2003) ISBN: 9780781737975 -, 4. A lateral submandibular approach to the upper cervical spine was used and careful bone resection was possible with a radiofrequency assisted burr and no instrumentation or fixation was required. Lumbar X-ray showed mild height loss and fracture of the superior endplate of T12 vertebra (Fig. Ganglion and synovial cysts are benign lumps caused by a buildup of fluid in a tendon sheath or joint capsule. Gas measures about -580 to -1000 HU in density 3. The radiological report should include a description of the following 7: imaging characteristics e.g.
Appearances on MRI are less definitive than on CT. Gas appears as low signal/signal void on both T1 and T2, and so appears similar to sclerotic bone. Aneurysmal bone cysts commonly present with pain and swelling. ADVERTISEMENT: Supporters see fewer/no ads. Summary of 2 new cases and 21 reported cases of bone cyst of lumbar vertebral body. Normal red marrow on DCE (dynamic contrast-enhanced) MRI time intensity curves (TICs) shows a slow wash-in, low maximal peak, and either minimal or no apparent washout. 4, pp. Primary bone tumors are rare. Pathology report confirmed the diagnosis of SBC and the patient received no further treatment (Fig.
