Parasitosis has been decreasing as health conditions were tried to improve. Infestation of the human brain with the larval stage of Taenia solium is clinically a great problem because of having symptoms such as convulsion, paralysis, and psychosis etc. Sixty-year-old man who had lived at Miyako island was undergone further examination for convulsive episodes of 36 years in history. CT scanning demonstrated multiple calcified spots in the brain. Immunological analysis showed high titer in Cysticercus. Right frontal craniotomy was performed and a small (1.2 × 1.5 cm) white gritty nodule adhering to the pericallosal artery was surgically removed. Photomicrographs of the nodule showed a scolex with four suckers and hooklets which confirmed the diagnosis of cerebral cysticercosis. In this case the fallowings were summarized; 1) the lesion exists in subarachnoid space around the cortex, 2) immunological analysis will help to make a preoperative diagnosis, and 3) surgical excision is to be performed, when the lesion is pathogenetic to intractable symptoms.
