Key Clinical Findings & Highlights
- Details posterior thoracic decompression and instrumented stabilization.
- Demonstrates complete curettage of expansile spinal osteolytic lesions.
- Ensures long-term structural spinal stability in young patients.
Abstract
Introduction & Background
ABCs account for approximately 1.4% of primary spinal bone lesions. Their vascular nature and propensity for rapid expansion require aggressive operative stabilization and thorough curettage to prevent recurrence.
Clinical Case Presentation & Diagnosis
A 16-year-old adolescent presented with progressive mid-thoracic back pain, paraparesis (motor power 3/5), and sensory loss below T6. Spinal CT and MRI revealed an expansile osteolytic lesion with characteristic 'soap-bubble' appearance and multilocular fluid-fluid levels involving the T5 posterior elements and pedicle with severe spinal cord indentation.
Surgical Technique & Management
Posterior midline exposure, T4-T6 pedicle screw instrumented stabilization, complete T5 laminectomy, and meticulous intralesional curettage of the hypervascular cyst lining were performed, followed by structural autologous bone grafting.
Discussion & Literature Context
Preoperative identification of fluid-fluid levels on T2 MRI is characteristic. Combining rigid instrumentation with complete curettage ensures immediate spinal biomechanical stability and long-term recurrence-free survival.
Conclusion
Surgical excision with instrumented fusion is the gold standard for thoracic aneurysmal bone cysts causing neurological deficit.
