title: Significant envenomation from a preserved rattlesnake head (in a patient with a history of immediate hypersensitivity to antivenin).
abstract: We present a case of significant envenomation from a severed, preserved rattlesnake head in a 22-year-old man. The patient was treated successfully with 15 vials of Crotalidae polyvalent antivenin despite a history of severe immediate hypersensitivity reaction to antivenin. The patient developed a mild case of serum sickness five days after antivenin infusion that was treated successfully with a course of steroids. The patient experienced complete recovery. This case demonstrates the hazard of even preserved snake heads and fangs.
