Glioblastoma status post surgery and radiation therapy. There has been interval evolution postsurgical changes related to left frontotemporal craniotomy with mild enhancement along the margins of the insular lobe resection cavity and susceptibility effect within the resection cavity. Otherwise, there is no significant change in the extent of the confluent T2 hyperintensity in the remaining portions of the left insula and anterior left temporal lobe. There is no evidence of acute infarct. The ventricles and basal cisterns 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.
Interval evolution postsurgical changes with mild nonspecific enhancement along the margins of the insular lobe resection cavity. Otherwise, no significant change in the residual T2 hyperintense portions of the tumor in the left insula and anterior left temporal lobe.
