Cauda equina syndrome (CES) is a rare but possible complication of neuroaxial anesthesia. Damage to the nerve roots may occur due to compression, inflammation, stretching, direct trauma, spinal ischemia or neurotoxicity, usually with lidocaine or bupivacaine. We describe a case of a 33-year-old patient that underwent an uneventful cesarean section with a combined spinal-epidural technique anesthesia, with levobupivacaine. 48 h after the procedure, she presented diminished muscular strength and abolished osteotendinous reflexes in the left lower limb, limited flexion of the right hallux, urinary retention and saddle anesthesia. Imaging exams excluded hematoma, thickening or compression of the cauda equina nerve roots. CES was suspected and treatment was initiated. 9-month follow up revealed diminished osteotendinous reflexes on the left lower limb and perianal hypoesthesia. Despite being unusual, neurological complications require prompt recognition and management to avoid permanent damage.
