The subdural extramedullary angiolipoma: A rare case report and review of literature

Spinal angiolipomas are benign uncommon tumors with the well-differentiated fatty tissue and copious abnormal vascular elements. The epidural angiolipoma accounts for more than 90% of all reported cases. We present a rare case of intradural extramedullary angiolipoma studied by CT and MRI imaging and reviewed the relevant literature. The bilateral L4-S1 laminectomy was performed. No serious complication occurred postoperatively and lambosacra MR imaging revealed no recurrence 1 year after surgery.
