The MRI sequences demonstrate dilated tortuous flow void vessels beneath the scalp of the left parietal region, representing an arteriovenous malformation (AVM). Note dilatation of the superficial temporal artery, and its parietal branch as well as the occipital artery supplying the nidus of the AVM. The draining veins are also visualized. No underlying bony abnormality nor communication with the intracranial circulation.
