 There are postoperative findings related to prior craniotomy for resection of a right parietal arteriovenous malformation. There is minimal residual T2 hyperintensity surrounding the resection cavity compatible with gliosis as well as ex vacuo dilatation of the right occipital horn. There is also thin residual enhancement adjacent to the resection cavity compatible with granulation tissue. There are no dilated flow voids in this region. There is no evidence of acute intracranial hemorrhage or acute infarct. There is no hydrocephalus, midline shift or herniation. The major cerebral flow voids are intact.
Expected evolution of postoperative findings related to resection of a right parietal arteriovenous malformation. No new flow-voids are seen to suggest residual or recurrent AVM.
