GBM. There is redemonstration of postoperative changes from previous resection of the right anterior temporal lobe, a portion of the right insula, and right inferior frontal lobe. Overall, there is no significant interval change in appearance of the scattered areas of nodular enhancement along the lateral ventricular margins.Extent of surrounding T2/FLAIR hyperintensity along the cavity margins extending posteriorly remains unchanged, with ex vacuo dilatation of the right lateral ventricle. Ill-defined T2/FLAIR hyperintensity along the left lateral ventricular margins is also stable. There is no diffusion abnormality to suggest recent ischemia. No extra-axial fluid collection is identified. There is no midline shift or mass effect.There is mild mucosal thickening in the right maxillary sinus with a mucosal retention cyst in the left. Mild fluid is noted in right mastoids.
1.Continued stable appearance of the resection cavity.2.No significant change in scattered areas of nodular ependymal enhancement along the lateral ventricular margins.
