8-year-old male status post DNET tumor resection. Redemonstrated are changes from recent right pterional craniotomy consistent with resection of the right anterior temporal lobe lesion. Fluid with air and minimal blood products are present intracranially without hematoma. There is residual T2 hyperintense parenchyma along the posteromedial aspect of the resection cavity. Linear T2 hyperintensity with some susceptibility is present along the previous location of 2 depth electrodes. Overlying smooth dural enhancement is felt to be postprocedural. The ventricles are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits are grossly unremarkable. Again noted is minimal fluid signal within the bilateral mastoid air cells.
