Surgical Treatment of Spinal Extradural Meningeal Cyst:

A Case Report

Abstract

Intraspinal extradural meningeal cysts are uncommon causes of spinal cord and nerve root compression. We report our experience of a 32-year-old male presented with progressive intermittent back pain. Magnetic resonance image and computed tomography myelography showed an extradural meningeal cyst extending at the T11-12 levels in the thoracic area. The cyst was confirmed as a Type I spinal meningeal cyst via the hemilaminotomy. Total resection of the cyst was not performed because the separation of the cystic bottom was difficult due to adhesion in the surgery. Surgical partial resection of the cyst wall and closure of the dural defect provided a favorable result.
