Male, 45 years old, with GBM, post RT evaluation. Postoperative findings are seen compatible with resection of a tumor at the left parietal-occipital junction. Extensive edema surrounding the tumor bed seen on the prior examinations has resolved. Only mild persistent T2 hyperintensity is present immediately surrounding the resection cavity. Several foci of enhancement are seen scattered along the margin of the resection cavity. The largest is found posteriorly and measures up to 8 mm. Brain parenchymal morphology and signal characteristics are otherwise unremarkable. No additional areas of tumor-like signal or enhancement are seen. The ventricles are normal in size and morphology.
Findings are seen compatible with resection of a tumor from the left parietal-occipital junction. Edema seen on the prior examinations has resolved. Only minimal T2 signal abnormality remains immediately surrounding the resection cavity. Several small foci of enhancement along the cavity margin are nonspecific. Attention on subsequent exams will be required.
