Computed tomographic and angiographic findings of 6 proven crebellar hemangioblastoma seen in this hospital during last 2 years were analyzed. The results were as follows : 1. Except one 14 years old female, all of them were 37 to 48 years old males. 2. The operative findings of the tumors were 3 cystic tumors with mural modules and 3 solid tumors. Computed toographic findings were : 3. Of three cases of cystic cerebellar hemangioblastomas. 2 cases revealed characteristic CT findings such as : a. In precontrast study, a well defined round lower density containing one isodense nudule in its periphery was seen in each cases. The abosrption coefficient of each lower density was around 5 EMI unit. b. In post contrast study, the nodules were enhanced densely and homogenoulsly while the lower densities remain unchanged. 4. Of three cases of solid cerebellar hemangioblastrom, 2 cases revealed isodense mass suggested by mass effect such as displaced 4th ventricle and peripheral edema in precontrast study, while the remaining case revealed ill defined slightly high density with peripheral edema. In postcontrast study, the 2 isodense masses showed well circumscrbed homogenous enhancement with central slight lower density in one of them, while high density mass revealed no enhancement at all. 5. The vertevbral angiography performed in 5 cases revealed high vascrlar tumors with feeding arteries , draining veins and increased circulation time. 6. The tumor blushing seen in vertebral angiogrphy was correlated to the postcontrast enhancement of solid tumors and mural nodules in cystic hemangioblastom.
