title: Neonatal cavernous angioma located in the basal ganglia with profuse intraoperative bleeding.
abstract: METHODS
  A rare case of congenital cavernous angioma detected during pregnancy is described. The tumor was pointed out by ultrasound in a fetus at 39 weeks gestation. The male baby was delivered by cesarean section. Computed tomography and magnetic resonance imaging revealed a tumor in the left basal ganglia. Because the tumor gradually enlarged and right hemiparesis became evident, a decision was made to remove the tumor. Because of profuse intraoperative bleeding, surgical total removal was not accomplished. Histopathological specimens revealed cavernous angioma. The patient was treated postoperatively with 30.4 Gy of local irradiation. His right hemiparesis improved and the tumor gradually decreased in size.
  
  
  CONCLUSIONS
  The literatures are reviewed and discussed about clinical features and management controversies of this rare tumor.
