We report 2 patients with arteriovenous malformation (AVM) associated with complete occlusion of the unilateral middle cerebral artery and moyamoya vessels. Xenon CT CBF study demonstrated diffusely decreased CMF in unilateral or bilateral hemispheres with multiple areas of decreased vascular reserve. A significant reduction of AVM size was seen in one patient who received radiosurgery with marked CBF improvement.
