[A case of XXXX : the effect of preoperative irradiation].

@entity5 @entity51 @entity10 @entity1653
A 30-year-old, right handed male was admitted with @entity10 and mild right-sided motor weakness of one year's duration. A CT scan revealed a mass over the left frontal convexity. A cerebral angiogram showed a huge, hypervascular @entity5 which was fed by bilateral external carotid and left internal carotid arteries. Because of its size and location, a surgical intervention was considered contraindicated at that time. Instead he was initially irradiated 52 Gy in total dose with 10MV x-rays (Lineac). A CT scan 4 months thereafter revealed remarkable decrease in the size of @entity5 and reduction of its mass effect. A CT scan 12 months later, however, revealed increase in low density area around mass, although the size of the @entity5 was much smaller than before. He was readmitted for surgery 14 months after irradiation. An angiogram visualized more reduction of @entity5 stain and the caliber of feeding arteries. The @entity5 was totally removed without resultant @entity51 . A histological diagnosis of the @entity5 was @entity1653 with well developed vascular networks. @entity1653 is usually not a radiosensitive @entity5 , but there are some reports of cases with @entity1653 which have been effectively treated with irradiation preoperatively. In the present case, because of a huge @entity5 in the dominant hemisphere, irradiation was given initial and 14 months thereafter the @entity5 was totally removed without @entity51 .
