Utility of Preoperative Magnetic Resonance Imaging Myelography for Identifying Dural Defects in Patients with Spinal Extradural Arachnoid Cysts: Case Report

Abstract

Because the preoperative MRI myelography scan correctly identified the existence and location of the dural defect, we conclude that MRI myelography is helpful for detecting dural defects in patients with epidural arachnoid cysts.
