[Idiopathic spinal cord herniation which extended remarkably up- and downward from dural defect: case report].
A case of idiopathic spinal cord herniation which extended remarkably up- and downward from a dural defect is described. A 53-year-old woman presented with numbness and pain of the right lower limb. Magnetic resonance (MR) imaging revealed ventral displacement of the spinal cord and dilation of the dorsal subarachnoid space at T4-5. CT Myelography showed ventral deviation of the spinal cord at the T4/5 level. A laminectomy of T3-T5 was performed, and the herniated spinal cord was untethered and wrapped by Goretex membrane. Postoperative MR image revealed normal location of the spinal cord. Among many cases of spinal cord herniations, this one is considered to be a rare case of idiopathic spinal cord herniation which showed marked protrusion up- and downward from a dural defect.
