Neurocysticercosis

Cysticercosis is a helmenthic infection involving pigs and man. Most cases of cysticercosis occur in developing countries. The disease is very rare in Islamic countries, as moslems are supposed to abstain from eating pork meat. In the last 10 years, reports of cysticercosis among moslems were published. Imigrants from endemic countries, who work as housemaids and food handlers played a role in transmitting the disease. Man becomes a definitive host if he ingests insufficiently cooked pork meat, which contains viable Iarvae of Taenia Solium or cysticerci. Neurocysticercosis denotes presence of a Taenia Solium larva cysts (Cysticercus cellulosae) in the brain parenchyma, meninges, or ventricular spaces. Neuroimaging by computerized tomography and magnetic resonance imaging are the best procedures to diagnose neurocysticercosis. Serological tests (EITB) or ELISA) are not sensitive as more than 50% of patients with neurocysticercosis have negative serology. Alpendazole and praziquentel are the most effective antihelmenthic drugs. Prevention of the disease and its complications as epilepsy is the management corner stone. A single dose of praziquentel for every emigrant from endemic areas will eradicate the adult tapeworm and reduce the incidence of neurocysticercosis. Physicians in moslem countries should be aware about the disease not only among immigrants but among moslems. We reviewed the available information about the disease epidemiologically, clinically, radiologically, laboratory tests, and methods of prevention.
