Abstract
Brain arteriovenous malformation (AVM) is an abnormal connection between arteries and veins, bypassing the capillary system in the central nervous system. The first symptom of AVM is intracranial hemorrhage, followed by headache and seizure. However, dizziness as a symptom of AVM is very rare. We report a 16-year-old female patient who presented with disequilibrium. She showed down-beating nystamgus on Dix-Hallpike test and falling tendency on Romberg test with eyes open. Magnetic resonance image showed cerebellar AVM.
