Delayed diagnosis of cerebellar hemangioblastoma after intracerebellar hemorrhage.

BACKGROUND: Cerebellar hemorrhage caused by cerebellar hemangioblastoma is not a frequent case. We report a case of solid, cerebellar hemangioblastoma, diagnosed 4 years after cerebellar hemorrhage. CASE DESCRIPTION: A 69-year-old man presented with dizziness and gait disturbance. He had a 4-year history of evacuation of cerebellar hemorrhage. Gadolinium-enhanced MRI revealed a well-enhancing mass in the left cerebellar hemisphere, and vertebral angiography revealed hypervascularity. Radiotherapy was given to the tumor bed. He remained stable for more than a year after radiation.
CONCLUSION: In cases of spontaneous cerebellar hemorrhage, particularly in the patient without hypertension or other underlying diseases related to bleeding from tumor, cerebellar hemangioblastoma should be suspected as a rare cause of hemorrhage, and computed tomography and/or MRI with contrast administration is mandatory for differential diagnosis.
