Abstract
About one of each 100 patients operated on after a diagnosis of low lumbar disc rupture prove to have a lumbar or sacral cyst as the cause of the symptoms. These cysts are located within a nerve or arise from the dura and compress adjacent nerves of the cauda equina. Cysts in a nerve may follow a sequence of nerve trauma, intraneural hemorrhage and intraneural cyst. A cyst may also result from inadvertently nicking the dura during removal of a nucleus pulposus with subsequent development of a meningocele-like lesion.
