A case of cerebral cysticercosis is reported. A 39-year-old male had a 20-year history of convul-sions. He had never travelled overseas. CT scan demonstrated a small calcified spot in the left tem-poral lobe and a ring-like enhanced area surrounded by perifocal low density in the left frontal lobe. Both lesions were sited in subcortical areas. The frontal lesion was removed and examined pathologically, matching it with the CT findings. The CT scan was very useful in the diagnosis of this disease. The possibility of cerebral cysticer-cosis must be raised, if intracranial punctate calcifications, ventricle dilatations, small low density areas in the parenchymal region, and low density areas with contrast enhancement are observed. In the case of cortical lesions, a well-enhanced capsule with both intracapsular enhanced structures and a cystic low density area may be important points for distinguishing this disease from a brain tumor or a brain abscess.
