Female, 63 years old, with GBM status post clinical investigation. Postoperative findings are redemonstrated status post lesion resection from the left parieto-occipital junction. A thin surgical tract through this region appears similar to prior. Rim-enhancing tissue in this region has not significantly changed. As before, enhancement extends along the ependyma of the left occipital horn. The degree of T2 hyperintensity and edema within the surrounding brain parenchyma, which involves portions of the parietal, occipital and temporal lobes, and the left genu of the corpus callosum, is also unchanged. No new enhancing lesions are seen. The left ventricular atrium remains displaced and partially effaced by lesional edema. Elsewhere, the ventricular system is within normal limits.
1.Redemonstration of postoperative changes related to prior lesion resection from the left parieto-occipital junction.2.The size and morphology of residual enhancing tissue in this area, as well as associated T2 signal abnormality, are unchanged.3.No definite disease progression is seen.
