Abstract

In this contribution the clinical features of eleven patients suffering from a neurinoma in the cauda equina and around the conus medullaris are analysed. Because of the relative mobility of the roots and the wide space in the spinal canal, tumours arising in the cauda equina or around the conus medullaris can become larger than any other spinal tumours. Lumbago was the predominant symptom as the initial complaint. Nocturnal pain relieved by walking was noticed in one patient. Two cases showed spontaneous remission and relapse. Vultiple tumours were found in 6 cases (55%). Macroscopic cyst formation was found in 5 cases (45%). Among the eleven patients, total removal of the tumour, including the involved root was performed in ten. The numbers of the resected nerve roots were one root in 6 cases, two roots in 2, and three roots in 2. Only one patient showed postoperative slight weakness of the leg.
