Grade III oligodendroglioma with 1p19q deletion, status post treatment. There are postoperative findings related to right frontal lobe tumor resection. There is unchanged confluent T2 hyperintensity along the margins of the resection cavity, as well as scattered foci of susceptibility effect in this region, but there is no abnormal nodular enhancement. There is also a small amount of confluent periventricular white matter T2 hyperintensity along the frontal horn of the left lateral ventricle. There is no evidence of acute intracranial hemorrhage or acute infarct. The brainstem and cerebellum appear unremarkable. The ventricles and basal cisterns are unchanged in size and configuration. There is a partially empty sella. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are unchanged.
No evidence of intracranial tumor progression.
