Black widow envenomation (latrodectism) is dangerous and important to recognize and treat in the emergency department. Latrodectism can mimic acute abdomen and, in severe cases, cause seizures and respiratory distress. Antivenom is indicated in severe cases and in special populations including the young, elderly, and pregnant. This chapter discusses a patient who presents to the emergency department complaining of nausea, cramping, and severe pain in the legs and abdomen. He reports a spider bite while working in a wood pile. The chapter discusses the physical exam, testing, diagnosis, and treatment plan for latrodectism, which includes wound management, pain control, tetanus update, and observation.
