Five cases of @entity438 are reported with special emphasis on the initial CT findings of these cases. One case was already reported by Endo (1974). The cases are three in @entity1 and two in adults, male four cases and female one case. Four cases had @entity6075 , one open. Consciousness level on admission were diversely from clear to semicomatose. Three cases experienced @entity397 of @entity439 . Time of diagnosis from @entity130 was from two days to 34 days. Location of @entity439 were near the junction of callosomarginal artery three cases, frontopolar artery one case, and A1-A2 junction one case. Operation was performed in four cases. Results were good in three cases and fair in a case. A case of no operation had fracture of anterior skull base and died from massive @entity1415 . Autopsy showed an @entity439 of A1-A2 junction, extending to sphenoid sinus. Histological findings of aneurysmal walls were @entity2849 in all cases. There were 48 cases of @entity438 in the literature. Most of cases are near the junction of callosomarginal artery. As the etiology of the @entity439 it is said that falx cerebri damages the arterial wall. We consider tear of junction of callosomarginal artery is a important factor, since the brain can easily move at the anterior portion of falx. It is very difficult to diagnosis traumatic @entity439 before @entity397 . But in our three cases of @entity438 , computed tomographies of very early stage of @entity130 showed interhemispherical high density area, @entity1410 and @entity548 of corpus callosum.(ABSTRACT TRUNCATED AT 250 WORDS)
