Resection of CCM on 4/23/15. There are postoperative findings related to right frontal craniotomy. There is a cavity in the right gyrus rectus region with linear susceptibility effect along the margins and mild confluent T2 hyperintensity in the surrounding white matter. There is diffuse mild thickening and hyperenhancement of the overlying dura. There is an unchanged punctate cavernous malformation in the pontomedullary junction. There are multiple nonspecific scattered foci of cerebral white matter T2 hyperintensity. There is no evidence of acute infarct or acute intracranial hemorrhage. The ventricles are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits are grossly unremarkable.
1. Postoperative findings related to right frontal lobe cavernous malformation resection with mild susceptibility effect along the margins of the resection cavity, which is likely attributable to residual blood products from the surgery.2. Unchanged punctate probable cavernous malformation in the pontomedullary junction.
