Multiple Mononeuropathy following Crotalid Envenomation: A case report

Abstract

ABSTRACT A 34-year-old man developed severe envenomation after being bitten by a Crotalus durissus (rattlesnake), which was treated with anticrotalic serum. Three weeks later, the patient reported paresthesia and neuropathic pain in the left hand, which had progressed to all four limbs. Electroneuromyography revealed asymmetric axonal sensorimotor multiple mononeuropathy. The patient was treated with prednisone, and six months later there was significant improvement in sensorimotor conduction. This is the first reported case of multiple mononeuropathy associated with C. durissus envenomation. Post-snake envenomation peripheral neuropathy is a rare complication requiring prompt recognition and treatment to optimize nerve function and enhance patient outcomes.
