Brain arteriovenous malformations (AVMs) are an abnormal vascular web that comprises the nidus, feeding arteries, and draining veins. The frequently used grading system is Spetzler-Martin grading. The majority of the brain AVMs are usually asymptomatic, but the common presentation can be headache, seizure, intracerebral hemorrhage, or focal neurological deficit. A 27-year-old male presented with the chief complaint of headache with episodes of ataxia over the course of 4–5 months. Magnetic resonance imaging (MRI) findings revealed multiple tortuous vessels with central nidus in the right posteroinferior cerebellar hemisphere. Also on contrast-enhanced computed tomography (CECT) brain angiography, area of the dilated tuft of vessels in the right posteroinferior cerebellar hemisphere with a nidus of vessels within brain parenchyma with arterial feeders and draining veins was observed. Computerized tomography (CT) of the brain angiography is a modality of choice for the depiction of feeding arteries and draining veins.
