Bilateral posterior circulation stroke secondary to a crotalid envenomation: Case report

Abstract

Snake bite envenoming is a disease with potential serious neurological complications. We report a case of an adolescent who wasbitten by a rattlesnake and developed bilateral posterior circulation stroke. The rattlesnake was later identified as being Crotalus durissus terrificus. Stroke was probably due to toxic vasculitis or toxin-induced vascular spasm and endothelial damage.
