Neurocysticercosis in the infant of a pregnant mother with a tapeworm.

Taeniasis occurs after ingestion of undercooked pork infected with cysticerci. Most Taenia solium infections are mild; proglottids are rarely noticed in the feces. Cysticercosis develops with ingestion of eggs from a tapeworm carrier. Cysticercosis affects approximately 50 million people worldwide, and is seen mostly in Central and South America, sub-Saharan Africa, India, and Asia. We present a case of an 18-month-old child living in New York, who presented with seizures caused by neurocysticercosis. A family study found a 22-year-old mother, 7 months pregnant, positive for T. solium, which presented a management dilemma.
