 There is a new 13x12 mm mass-like focus of intense enhancement in the right lateral occipital lobe slightly inferior and lateral to the postoperative cavity with associated mild restricted diffusion and increased relative CBV. Surrounding hyperintensity couldThere is minimal enhancement along the resection cavity margin which is compatible with treatment change. There are postoperative findings related to right occipital mass resection with resolved pneumocephalus and decreased intrinsic T1 shortening along the surgical cavity and subjacent dural thickening with linear enhancement. There is persistent nonspecific and nonenhancing confluent T2 hyperintensity and mild mass effect in the right parietal and occipital lobes which is stable to slightly decreased.
1.New 12x13 mm solid enhancing nodule in the right lateral occipital lobe inferolateral to the resection cavity. There is mild restricted diffusion and some elevation in CBV. Although this patient has had recent radiation treatment, findings are suspicious for tumor progression. Suggest close follow-up.2.Evolution of right occipital resection cavity with mild enhancement in the resection bed which may represent treatment change.
