A) Brain MRI showed arteriovenous malformations (red arrow). B) MRA revealed severe abnormalities in anterior cerebral artery (red arrow). C,D) DSA confirmed the elongation and tortuosity in the A1 and A2 segments of right anterior cerebral artery (red arrow) and a small aneurysm formation in proximal end of anterior cerebral artery (red arrowhead).

Dynamic electroencephalogram (EEG) monitoring showed epileptiform discharge in right frontotemporal hemisphere and magnetic resonance imaging (MRI) of the brain showed arteriovenous malformations (Figure 1A). Magnetic resonance angiogram (MRA) revealed severe abnormalities in anterior cerebral artery (Figure 1B). Further, three-dimensional digital subtraction angiography (DSA) confirmed the elongation and tortuosity in the A1 and A2 segments of the right anterior cerebral artery and a small aneurysm formation in the proximal end of anterior cerebral artery (Figure 1C,D).
