Cauda equina syndrome is an important neurologic disorder characterized by lower back pain, sciatica, perineal numbness, and sphincter dysfunction. This article reviews the anatomy, clinical presentation, evaluation, and treatment of cauda equina dysfunction, focusing on diskogenic cauda equina syndrome. ⋯ In the absence of high-quality data indicating otherwise, urgent evaluation and intervention are required for diskogenic cauda equina syndrome. Other etiologies of cauda equina dysfunction including neoplastic, infectious, and iatrogenic causes must also be considered, especially in the setting of normal neuroimaging studies.
