Cauda Equina Herniation
The author describes a case of a 55-year-old man who presented with severe low back pain and paraparesis due to cauda equina herniation. Diagnosis was made with a suspected spinal fluid leakage in T2 weighted MR images. In surgery, herniated cauda equina roots through a rent of the dura mater were noticed and the dura was repaired. There has been no reports on idiopathic cauda equina herniaton and this is the first report.
