A case of neurocysticercosis presenting as focal seizure

: In Japan neurocysticercosis is a rare disease. We report a case of neurocysticercosis with a review of the literature. A 29-year-old man presented focal seizure on the left side. Physical and neurological findings on admission were unremarkable. CT and MRI showed a mass with ring-like enhancement and perifocal edema in the right frontal lobe, as well as multiple small masses with calcification. The main mass measuring 8 mm in diameter, was suspected as the eliptogenic focus, and was totally removed via the transcortical approach. Postsurgically seizures did not recur, and histological examination of the mass confirmed a cysticercus. A therapeutic course of albendazole and praziquantel administered postsurgically was effective for the multiple intraparenchymal masses.
