Female, 76 years old, with history of GBM, on Avastin status post re-RT. A small hemosiderin stained resection cavity is again seen at the right parieto-occipital junction. Nodular intrinsic T1 hyperintensity along the margin of the cavity is unchanged. A curvilinear region of intrinsic T1 hyperintensity is also stable more superiorly within the superior parietal lobule. No definite evidence of any superimposed enhancement seen at either of these sites, or anywhere along the resection cavity.Ill-defined T2 hyperintensity involving the tissues surrounding the resection cavity, as well as in the periventricular regions, right more than left, is unchanged. No new areas of signal abnormality or pathologic enhancement are detected. No evidence of parenchymal edema or mass effect is seen. Ventricular size and morphology are unchanged.
Stable examination with no evidence to suggest new or progressive disease.
