Neurocysticercosis: Migration of a Parasite

Thesis (M.Nurs.), College of Nursing, Washington State UniversityNeurocysticercosis is the most common parasitic infection of the central nervous system (CNS). Infection occurs following oral ingestion of eggs of the porcine tapeworm, Taenia solium.. Eggs migrate to distal tissue sites via the bloodstream, and develop into larval cysts. When cyst growth disrupts normal function of the CNS, patients most commonly present with new onset seizures or hydrocephalus. Neuroimaging with computed tomography (CT) scan and magnetic resonance imaging (MRI) is used to diagnose neurocysticercosis. Treatment regimens are based on cyst location and developmental stage, and include supportive care, supportive care combined with pharmacologic therapy, and surgical intervention
