Neurophysiological study in endometriosis: A case report of catamenial sciatica

Sciatic nerve endometriosis is a rare cause of sciatic injury; however, it is important to consider this diagnosis due to the high recognizability of patients with cyclic pain and the availability of specific treatment methods. In addition to the imaging studies, electroneuromyography should be performed to determine the localization, chronicity, and severity of involvement. Herein, we presented the detailed electrophysiological study of a 47-year-old female with sciatic endometriosis who underwent surgery with complaints of cyclic sciatica and sensory and motor deficits compatible with sciatic neuropathy, which showed incomplete improvement after intervention.
