Spinal aneurysmal bone cyst presenting as acute paraparesis during pregnancy

摘要

Aneurysmal bone cysts (ABC) are benign but locally aggressive osseous lesions characterized by blood-filled cystic cavities that account for 1-2% of all bone tumors. While pain remains the most common presenting symptom of spinal ABC, extensive anterior column involvement can result in vertebral fractures, spinal instability, and neurological deficits from compression of neural elements. An exceedingly rare case of thoracic ABC presenting as acute paraparesis in a 21-year-old pregnant woman, that was successfully treated with urgent surgical decompression and stabilization, is reported, with discussion of management strategies and review of the pertinent literature.
