Cysticercosis. Neurocysticercosis is the most frequently encountered parasitic infestation of the CNS. Originally endemic in underdeveloped countries, predominantly Latin America, Africa, Asia and some portions of eastern Europe, it is becoming increasingly frequent in North America in immigrant populations. Humans become accidental hosts for the larval stage of Taenia Solium, the pork tapeworm, by ingesting contaminated material. The eggs hatch in the stomach and larvae burrow through the gut wall and become distributed by the circulatory system. There is a predilection for involvement of the brain. Patients most often present with seizures, elevated intracranial pressure, focal neurologic abnormalities and altered mental status. Asymptomatic infections are common.
Neurocysticercosis in an Orthodox Jewish community in New York City. A cautionary tale of how people who don't eat pork can be infected with this pork tapeworm larva by Latin American recent immigrants who prepared their food. CONCLUSIONS. A diagnosis of neurocysticercosis should be considered in patients with seizures and radiologic evidence of cystic brain lesions, even in those who do not eat pork and who have not traveled to a country in which T. solium infection is endemic. Recent emigrants from countries in which T. solium infection is endemic should be screened for tapeworm infection in their stools before they are employed as housekeepers or food handlers.
Worms on the Brain. Dawn Becerra and her doctors believe the parasite got into her system three years ago, when she ate a pork taco while on a visit to Mexico. Becerra said she was ill for three weeks after eating the taco. Soon after, she began suffering violent seizures. Later, doctors determined she had a parasitic worm in her brain and it had caused neurocysticercosis - a lesion in her brain. Doctors at Arizona's Mayo Clinic in Scottsdale believe the taco contained Taenia solium, a parasite that is common in Latin America. It can be transmitted by infected food prepared by someone who has not followed proper sanitation procedures after coming into contact with the creature's eggs, which can be present in human feces.
