Intermittent cauda equina compression remains a diagnostic challenge. The authors have reviewed 30 operative cases and the literature, and conclude that the diagnosis can be made on clinical grounds only. A myelographic deformity, no matter how marked, is not diagnostic proof of this syndrome, nor is the absence of neurologic deficit. Decompression by laminectomy and medial face-tectomy brings about a gratifying result in most instances.
