Male, 64 years old, with history of GBM, on CCNU. The resection cavity incorporating the right anterior temporal lobe, a portion of the right insula on the right inferior frontal lobe has not significantly changed in size or morphology. T2 hyperintensity surrounding the resection cavity is unchanged.Thin enhancement along the medial edge of the resection cavity is unchanged. Thin ependymal enhancement along both frontal horns has diminished. Thin ependymal enhancement seen previously along the right atrium is no longer detected.No new enhancing or T2 hyperintense lesions are demonstrated. Ill-defined periventricular T2 hyperintensity along the left lateral ventricle has not significantly changed. Ventricular size and morphology are unchanged.
1.Stable appearance of the resection cavity.2.Diminished ependymal enhancement along the frontal horns could represent response to treatment.3.No new lesions are detected.
