Summary
Aneurysmal bone cysts (ABCs) of the spine are rare spinal tumors. This study details five unique vertebral body ABC cases, including a coccyx origin and severe complications, highlighting surgical management and preoperative irradiation.
Area of Science:
- Orthopedic Surgery
- Oncology
- Spinal Surgery
Background:
- Aneurysmal bone cysts (ABCs) are rare, benign bone lesions, infrequently occurring in the spine.
- Fewer than 100 cases of spinal ABCs have been reported in English literature, emphasizing their rarity.
Observation:
- This report details five cases of vertebral body ABCs, presenting diverse clinical scenarios.
- One case represents the first reported spinal ABC originating from the coccyx.
- Two cases involved large abdominal masses with significant bleeding during biopsy, and one presented with complete paraplegia.
Findings:
- All five vertebral ABCs were successfully resected using a one-stage anterior or combined anterior-posterior surgical approach.
- Preoperative irradiation was utilized in two cases to manage life-threatening bleeding, facilitating subsequent complete anterior excision.
Implications:
- These findings expand the understanding of spinal ABC presentation and management.
- The successful use of preoperative irradiation in bleeding cases offers a potential strategy for complex spinal ABCs.
- Surgical resection via anterior or combined approaches is effective for spinal ABCs, even in challenging presentations.
