== Clinical Summary ==

This 29-year-old woman was admitted to the hospital because of repeated tonic-clonic seizures. The patient was a tour guide leading groups of tourist to Tibet for two-month walking/camping tours in the Himalayas. Her seizures were easily controlled by intravenous administration of phenytoin. The WBC count was 13,000, with 5% eosinophils; the erythrocyte sedimentation rate was 19. A cranial CT performed with and without contrast revealed two ring-enhancing lesions. The patient underwent a craniotomy and excisional biopsy.

The WBC count was 13,000, with 5% eosinophils and the erythrocyte sedimentation rate was slightly elevated. A cranial CT performed with and without contrast revealed two ring-enhancing lesions. The patient underwent a craniotomy and excisional biopsy.

Histopathologic exam of the surgical specimen revealed a capsule of dense connective tissue surrounding a cavity that contained a partially degenerated scolex of Taenia solium.

== Study Questions ==

* <spoiler text="How did this patient get this parasite?">Cysticercosis is caused by the cestode parasite, Taenia solium (pig tapeworm). Cysticercosis is contracted by ingesting eggs from the feces of a person infected with an adult Taenia solium. The eggs can survive for several weeks in soil but are also infectious as soon as passed. The larvae migrate through the intestinal wall and are disseminated via the blood stream and can encyst in the brain, heart, skeletal muscle, or skin.</spoiler>
