Clinical features of cauda equina tumors requiring surgical treatment.

In this study, we evaluated the clinical features of cauda equina tumors requiring surgical treatment. Medical records of 28 patients with cauda equina tumors (13 men and 15 women) undergoing surgical treatment were retrospectively reviewed. The majority of histological diagnoses indicated schwannoma (23 cases, 82%), and the remaining 5 indicated ependymoma, neurofibroma, meningioma, and gangli...

The continuation of the spinal cord is a strand of connective tissue, the filum terminale. The ventral and dorsal lumbar and sacral nerve roots that arise from the conus medullaris form a bundle, the cauda equina (Figure 1). These lumbar and sacral spinal nerve roots separate...

Although well documented in the neuropathology and neurosurgery literature, only one case report has appeared in the radiology literature to date [1]. Recognition of the tumor is important because of its biologic characteristics ; which differ significantly from ependymoma, the tumor with which it is most commonly con...
