Lumbar Spine Aneurysmal Bone Cyst: A Rare Entity

2021

An Aneurysmal Bone Cyst (ABC) is a benign, locally aggressive, vascular, and expansile bony tumor of idiopathic etiology containing multiple thin-walled blood-filled channels, mostly diagnosed in pediatric and adolescent age groups. These lesions can cause local pain, pathological fractures, spinal deformity, and neurological deficits. The treatment of choice for ABC is highly debatable according to the literature. The treatment choices are simple curettage and grafting, complete surgical resection with or without prior selective arterial embolization, radiotherapy, or a combination of these procedures according to the case. Each modality is having different outcomes, technical requirements, and complications. We are reporting a case of Aneurysmal Bone Cyst of the lumbar spine in a young patient treated by surgery.

Uncommon Presentation of Aneurysmal Bone Cyst in Spine Involving Vertebral Body

Journal of Evolution of medical and Dental Sciences, 2015

INTRODUCTION: Aneurysmal bone cyst of the spine was first described by Jaffe et al in 1942. An aneurysmal bone cyst (ABC) is a non-neoplastic expansile and locally destructive highly vascular bone lesion characterized by channels or spaces filled with blood and separated by fibrous septa. It usually involves long bones. Its occurrence in spine is rare, and usually involves posterior elements, while involvement of body is very rare. MRI and CT are the imaging modalities of choice in the diagnosis of bone cysts in the spine. Although regarded as benign tumors, ABCs can be locally aggressive, causing profound destruction of their encasing bones and pathological fractures, as well as compression of adjacent vital tissues from their rapid expansion. For this reason, ABCs of the spine, due to their close proximity to the spinal cord and nerve roots, warrant special attention and present a unique clinical challenge. We are reporting this case with ABC of thoracic spine involvement which wa...

The aneurysmal bone cyst (ABC) is a fast-growing tumor of undefined neoplastic nature. It is occasionally an aggressive benign lesion whose treatment of choice is a complete resection, even though the risk of profuse transoperative bleeding exists. We present a female patient with thoracic spine deformity, with progressive paresthesias and muscle weakness of lower extremities that evolved to paralysis of both lower extremities and sphincter incontinence. Based on radiographic films, lytic lesions were identified at T7 to T9 vertebrae as well as medullary space invasion. In electrophysiologic tests, a complete somatosensorial pathway block was reported. Prior to resection of the neoplastic lesion and thoracolumbar stabilization, an incisional biopsy was performed. There was no postoperative medullary functional improvement. Morphological findings corresponded to an aneurysmal bone cyst at T8. This lesion is mainly located in the long bones and less frequently of the spine, where inst...

Aneurysmal Bone Cysts of the Spine in Children: A Review of 18 Cases

Global Spine Journal, 2019

Study Design: Retrospective study. Objective: The aim of this study was to evaluate the clinical presentation, treatments, outcome, complications, and recurrence rate in the surgical and nonsurgical management of spinal aneurysmal bone cyst (ABC) in a series of 18 pediatric patients. Methods: Between 1988 and 2014, we evaluated 18 pediatric patients diagnosed with ABC confirmed by pathology studies. We analyzed clinical and radiological features, non-surgical and surgical treatment, outcome, and complications. Results: The series included 12 male and 6 female patients with a mean age of 10 years and 4 months, with a mean follow-up of 5 years. Location of the ABC was lumbar in 8, cervical in 7, thoracic in 2, and sacral in 1 case. Axial pain was the most common symptom followed by radicular involvement. Surgery was performed in the presence of spine instability or neurological involvement (tumor resection) and in the remaining, nonsurgical treatment (percutaneous intralesional inject...

Aneurysmal Bone Cysts of the Spine: Two Case Reports

Korean Journal of Spine, 2014

Aneurysmal bone cysts are rare entities which causes expansile and destructive bone lesions characterized by reactive proliferation of connective tissue. They usually grow rapidly with hypervascularity. In clinical practice they can be easily misdiagnosed due to the rare occurance and having no such typical findings as radiologically. Most cases have uncommon pain symptoms, but rarely, if fractures occur, neurological findings can be seen and the surgical treatment, if needed, could be difficult. We will discuss our evaluations to two cases that we experienced in our clinic in this report.

Aneurysmal bone cyst of the spine: 9 pediatric case report

Romantisme, 2020

Purpose: Aneurysmal bone cysts are benign and expansile osteolytic lesions that can occur in any location in the spine. This report describes clinical characteristics and treatment results of 9 young patients with aneurysmal bone cyst of the spine. Methods: Between 1997 and 2015, 9 young patients with aneurysmal bone cyst of the spine were surgically treated in our department. The clinical records, radiographs, and operative reports were analysed. Results: This study included 9 paediatric cases (6 girls, 3 boys) managed for aneurysmal bone cyst. The mean age was 11 years. Posterior spinal elements were affected in all cases. The lesion affected the cervical spine (1 case), thoracic spine (3 cases), and lumbar region (5 cases). The radiological aspect was typical in all cases. MRI imaging was very suggestive of the diagnosis showing specific features of the lesion. It was described as an expansil lytic process arising from vertebral posterior elements. All patients underwent a surgical removal of the tumor following a surgical biopsy. A segmental instrumented fusion in order to establish a proper spinal stability was made in 5 cases. Histological report confirmed the diagnosis of aneurysmal cyst in all patients. The mean follow-up was 7, 7 years. The follow-up course was uneventful. Conclusion: The presented study demonstrates that lesional resection and structural spinal integrity made by local spinal fusion allow good outcomes with a low rate of complications and low recurrence.

A 35yrs young patient, presented to the hospital with lower extremities neurological deficit, radiological investigation showed bony lesion in the posterior elements of T 10 causing severe compression on the cord, emergency surgery was performed to decompress the spinal cord, the microscopic examination revealed that lesion was " aneurysmal bone cyst".

Solid variant of aneurysmal bone cyst on the cervical spine of a child: case report, differential diagnosis and treatment rationale

European Spine Journal, 2013

Introduction Despite numerous descriptive publications, the nature, character, differential diagnosis and optimal treatment of aneurysmal bone cysts (ABCs), remain obscure. The authors report a case of the solid variant of aneurysmal bone cyst (S-ABC) occurring in the posterior components and body of C7 vertebra focusing on the differential diagnosis and surgical treatment rationale. Case report Right shoulder and neck pain were the presenting symptoms of 9-year-old boy. Torticollis developed later on but no neurological deficit was found. Imaging revealed an osteolytic lesion with significant extraosseous extension. Although diagnosis favoured an ABC, imaging studies did not provide clear diagnostic criteria. CT guided biopsy performed preoperatively was also not directly diagnostic. Given that differential diagnoses included S-ABC but also giant cell tumor (GCT) of bone, decision was made to proceed with a staged, back and front, complete resection of the affected bony elements of C7. Preoperative spinal angiography showed supply to the tumor from the right ascending and deep cervical artery territories. Particle embolization was not performed due to the presence of ipsilateral supply to the anterior spinal artery at the C6 level and contralateral supply at the C7 level. Intraoperatively, histology taken from posterior elements, although again not clearly diagnostic, favoured S-ABC variant rather than GCT. Thus, initial plan was revised and anterior surgery was postponed as the extent of the dissection would have been dependent on the presumed diagnosis. The final histological report confirmed the diagnosis of an S-ABC. In view of this, it was decided to embolize the lesion to avoid a second stage anterior surgery. At embolization, repeat spinal angiography showed reduced tumor blush following the surgery. Distal branches of the deep cervical artery were occluded with platinum coils (avoiding the risks associated with the use of particles or liquid embolic agents). No further procedure was planned. Conclusion Imaging and histological pattern of this specific type of ABC, differential diagnosis from GCT and the surgical protocol followed with the patient consist of an interesting case of revising the initial plan, according to the upcoming histological reports.
