Extradural cyst causing spinal cord compression in osteoporotic compression fracture.

Abstract

Intraspinal cystic lesions with different pathogeneses have been reported to cause neurological deficits; however, no one has focused on the intraspinal extradural cysts that develop after osteoporotic compression fracture. The reported case features a 66-year-old woman presenting with progressive neurological deficit, back pain, and no history of additional trauma after undergoing conservative treatment for an osteoporotic fracture of L-1. The authors present serial radiographs and MR images demonstrating an epidural cyst successfully treated via a single posterior approach. This appears to be the first such case reported in the literature.
