Cysticercosis is a disease transmitted by the ingestion of the eggs of the worm Taenia solium. It is the most common parasitic disease in humans and its incidence is not increased in patients with AIDS. 1 In addition, cysticercosis is rapidly becoming the most important cause of acquired epilepsy throughout the world. Although in the past, cysticercosis occurred mostly in third-world countries, its distribution is now worldwide, reflecting changes in immigration. The most important aspects in the management of patients with cysticercosis are the availability of CT and MRI for its diagnosis and follow-up, the availability of serodiagnostic assays that help to confirm the diagnosis, and introduction of specific antiparasitic agents. 2 The enthusiastic use of brain imaging and serologic studies have lead to a dramatic increase in the estimated numbers of affected individuals.
