[Multiple recurrences of cerebellar hemangioblastoma after 20 years from initial total removal of the tumor].

Cerebellar hemangioblastoma develops alone or develops as part of von Hippel-Lindau disease. Moreover, multiple hemangioblastomas are found in 10-15%. It was reported that some hemangioblastomas recur with multiple recurrence in long time follow-up period. A 51 years old male was referred to our hospital because of headache and found a cerebellar tumor which was totally removed and diagnosed as hemangioblastoma pathologically. He presented no deficit after first surgery, but he did not come our hospital. In May 2000, he was referred to our hospital because of headache again and found five cerebellar tumors on MRI. Angiography showed markedly tumor stain. Retinal and spinal lesions were not seen. Two of five tumors was removed. The remaining three small tumors were received gamma knife surgery. In December 2000, because of cyst enlargement, one tumor was removed and the cyst was opened. In June 2001, he presented right hearing disturbance due to enlargement of cerebellar pontine angle tumor. The tumor was removed after tumor embolization, but hearing disturbance and slight dizziness remained. The remaining 5 mm tumor is followed.
