title: [A case of high-aged idiopathic spinal cord herniation from dural defect].
abstract: Idiopathic spinal cord herniation was assumed to be a rare disease. However, the incidence of discovering this condition appears to have been increasing recently with advances in neuroradiological diagnosis using magnetic resonance imaging (MRI) and computed tomographic myelogram (CTM). We present herein an operated case of high-aged idiopathic spinal cord herniation. A 71-year-old female presented with spastic paresis of the right lower limb and sensory disturbance of pain and temperature below the level of the left Th4 dermatome, consistent with Brown-Séquard syndrome. MRI and CTM revealed right ventral displacement of the spinal cord and dilatation of the dorsal subarachnoid space at Th2/3. Laminectomy of Th1-3 was performed, herniated spinal cord was untethered and repositioned, and the dural defect was sealed with GORE-TEX dura substitute. Postoperative MRI revealed normal location of the spinal cord and neurological state improved slightly. The patient was discharged 1 month after the operation. Among many cases of spinal cord herniations, this is considered to be a rare case of idiopathic spinal cord herniation in an elderly patient.
