けいれんで発症した脳石症の2手術例

Abstract

<Case 1> A 49-year-old man had a sudden onset of generalized convulsion. No finding was gained through neurological testing. Skull X-ray film and plain CT-scan revealed a calcified mass in the right frontal lobe. Bemegride activated EEG showed focal abnormal wave discharge in the right frontal lead. The patient underwent the surgical operation with the aid of electrocorticogram. Histopathological examination demonstrated that there was an atrophic cerebral tissue localized around the stone. <Case 2> A 42-year-old woman suffered from temporal epilepsy for several years. Every effort had been made to cope with the seizures but in vain. Incidentally a calcified mass was disclosed in the right temporal lobe through CT-scan. The patient then underwent a surgical operation. Histopathological examination was carried out and it was diagnosed as cavernous hemangioma. The paper presents 2 surgical cases where the onset of convulsive attack was attributable to brain stone. We review several previous reported cases and examine the problems of the surgical treatment of brain stone.
