A 55-year-old male with sudden onset of transitory aphasia. a DWI (b-factor 1000) shows an area of restricted diffusion in the left parietal region. b PD-weighted SE image shows an AVM in the pineal region. c DSA proves a combined pial-dural AVM. Although the precise pathogenesis of acute neurological symptomatology in a patient with an AVM is unknown, the “steal phenomenon” may play a role in its development. DWI, diffusion-weighted imaging; PD, proton density; SE, spin echo; AVM, arteriovenous malformation; DSA, digital subtraction angiography
