Clinical Analysis of Hemangioblastoma

ABSTRACT

Hemangioblastomas are solid or cystic benign vascular tumors that may arise anywhere in the body. In the central nervous system, they are rare, accounting for only 1-2.5% of all intracranial neoplasms. The purpose of this report is to investigate the postoperative natural history of hemangioblastomas. Since 1987, 13 patients with this condition have been diagnosed and have undergone surgery at this hospital. In all cases, the tumor(mural nodule or solid tumor) was completly removed. The mean post-surgical follow-up period, during which time three patients underwent radiation therapy, was 28.5 months. Ten patients completily recovered, without neurological deficits, and in three, there was mild disability with some neurological deficits; mild paralysis of the vocal cords, transient paralysis of the facial nerve, and cerebellar dysarthria were noted, but these patients had on difficulty in resuming their normal life. In every case, the outcome was successful and during the follow-up period, the condition did not recur.
