Abstract

Cysticercosis, a brain infection caused by the parasite Taenia solium, presents considerable health challenges, especially in tropical and developing areas, where it contributes significantly to the incidence of epilepsy. The lifecycle of this parasite involves humans as the primary hosts and pigs as the intermediate hosts. In this case study, a 12-year-old girl exhibited unusual symptoms, such as fainting episodes and a decline in academic performance. Although she adhered to a vegetarian diet, her contact with pigs resulted in an infection, confirmed by a CT scan that revealed a cyst in the right frontal lobe containing a hyperdense scolex. The treatment regimen included valproic acid, prednisolone, and albendazole, which successfully resolved her seizures over a follow-up period of 24 months. This case underscores the diagnostic challenges associated with cysticercosis and highlights the necessity of identifying atypical cognitive symptoms related to this infection, particularly in populations at risk of exposure.

Keywords: albendazole; attention-deficit; cysticercosis; frontal lobe; taenia sodium.
