Review Case Reports[A case of idiopathic herniation of the spinal cord associated with duplicated dura mater and with an arachnoid cyst].
Idiopathic herniation of the spinal cord is a very rare disease, only 2 cases being so far reported in the literature. A 61-year-old man with a gradual loss of power in his lower extremities was diagnosed as intradural arachnoid cyst, and underwent operation. ⋯ Although this dural inner layer as well as the arachnoid cyst was resected, his clinical symptoms remained unchanged after operation. When a shift of the spinal cord is detected in an image, we should precisely determine the relationship between the spinal cord and the dura mater during operation with consideration of a possibility of the presence of idiopathic herniation of the spinal cord.
