Cerebellar hemangioblastoma is the most common highly vascular tumor of the posterior fossa tumor in adult. Four cases of the cerebellar hemangioblastoma which were diagnosed at Seoul National University Hospital during last six years were presented with analysis of characteristic findings of the cerebellar hemangioblastoma in vertebral angiography. The results are as follows: 1. There patients were male and one was female. All cases were distributed from late third decade to early fifth decade. 2. Simple skull series show no significant abnormality. 3. Vertebral angiographic findings: The tumor was solitary. Location of the tumor was midline of the posterior fossa; inferior vermis and fourth ventricle. Feeding artery was posterior inferior cerebellar artery. Abnormal tangle of tumor vessels were noted. Three cases were solid type and one was cystic with mural nodule. Abnormal circulation pattern with increased circulatory rate and early filling of drain vein were demonstrated Tumor stain was non-homogenous conglomerated vascular network. These findings were seen in all cases. Therefore, vertebral angiography plays a specific and definitive role in the diagnosis of this tumor.
