Abstract

Pial arteriovenous fistula (AVF) is an extremely rare intracranial vascular lesion. The pediatric type of AVF has a high percentage of varix, leading to mass effect with symptoms. We report a 12-year-old boy who was admitted due to sudden confusion and urinary incontinence. Computed tomography, magnetic resonance imaging, and magnetic resonance angiography (MRA) confirmed the diagnosis of congenital pial AVF. Digital subtraction angiography (DSA) revealed the lesion originating from the left middle cerebral artery and draining into the superior sagittal sinus. The AVF was successfully obliterated with six microcoils and 2.5-mL ethylene vinyl alcohol copolymer using a middle cerebral artery approach. This patient was discharged without neurologic deficits. The AVF became smaller and ultimately disappeared on the DSA and MRA at follow-up.
