Minimally Invasive Surgery of Spinal Extradural Arachnoid Cyst with High-Resolution Myelography: A Case Report

Abstract

Spinal extradural arachnoid cyst (SEAC) is a rare disease, and symptomatic cases are even rarer. Symptoms can affect the quality of life of a patient due to compression myelopathy, radiculopathy, and pain. Treatment is often necessary for symptomatic SEACs, but no standard treatment has been established. We report a young symptomatic SEAC patient with both radiating leg pain and gait disturbance for several years. She was successfully treated with minimally invasive surgery through precise preoperative localization of the dural defect with high-resolution myelography and magnetic resonance imaging. Accurate and precise diagnosis is essential for successful minimally invasive surgical treatment of symptomatic SEAC.
