Two Cases of Cerebellar Hemangioblastoma with Isolated Vertigo / 대한평형의학회지

ABSTRACT

Hemangioblastoma is solid or cystic benign vascular tumor that may arise anywhere in the body. It is rarely presented tumor accounting for only 1% to 2.5% of all intracranial neoplasms. Usually, hemangioblastoma is located in the cerebellum and posterior cranial fossa and it occurs in a variety of symptoms depending on where the tumor is located. The initial symptoms in 80% to 90% of hemangioblastoma patients are headache and vomiting due to elevated intracranial pressure, and also dizziness and balance problems are initially presented in about half of the patients. We experienced 2 cases of hemangioblastoma who presented with isolated vertigo. All of them initially showed unidirectional spontaneous nystagmus during head impulse test. Finally, hemangioblastoma of the cerebellum has been diagnosed on magnetic resonance imaging scan. In one case, the tumor was successfully removed by retrosigmoid approach and the other case was treated conservatively due to pregnancy.
