Tumors of the cauda equina-conus medullaris region are often well-defined, small masses attached to the filum terminale. These lesions are dissected from the nerve roots and the tip of the spinal cord relatively easily. A portion of uninvolved filum terminale is usually present between the tumor and spinal cord. The afferent and efferent segments of the filum must be amputated to remove the tumor. Small and moderate-sized tumors do not require internal decompression. Recurrences after successful en bloc resections are rare.
