Male, 75 years old, with GBM, follow-up examination. Postoperative changes are again seen compatible with left temporal/parietal craniotomy and tumor resection. The treatment bed shows a dense accumulation of susceptibility effect likely representing chronic hemosiderin, unchanged.Ill-defined T2 hyperintensity surrounding the treatment bed and extending through the left temporal, occipital, parietal and frontal lobes is unchanged. Irregular enhancement within the treatment bed centered on the ventricular atrium has not significantly changed in size or extent. Ependymal enhancement along the left occipital horn may be minimally thicker when compared to prior examination but this could also be technical in nature.No new enhancing or T2 hyperintense lesions are seen. Ill-defined T2 hyperintensity around the right lateral ventricle, and scattered small foci elsewhere in the brain, are unchanged. Ventricles are stable in size and morphology.
No definite or significant interval change is seen in the size and distribution of irregular enhancement in the left parietotemporal treatment bed. Ependymal enhancement along the left occipital horn may be minimally increased in thickness but this could also be technical.
