IDIOPATHIC SPINAL-CORD HERNIATION

Idiopathic spinal cord herniation is a rare disease, few cases having been reported. We encountered a case of idiopathic spinal cord herniat ion presenting with severe spasticity in the right leg and urinary dys function. The spinal cord was herniated into a cavity created by dupli cation of the dura mater and resection of the inner layer improved the neurological deficits. MRI, myelography, and CT myelography were usef ul for diagnosing this disease. Four radiological signs of spinal cord herniation are described.
