Oligodendroglioma status post RT and now on PCV. There are post-treatment findings in the left temporal region with a persistent confluent, mildly expansile area of T2 hyperintensity and and susceptibility effect in the left temporal lobe with slightly increased patchy foci of enhancement, which may display corresponding slightly elevated perfusion. There is also an unchanged subcentimeter non-enhancing focus of T2 hyperintensity in the right superior cerebellar hemisphere. There is no evidence of acute intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. 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.
1. Slight interval increase in the patchy foci of enhancement associated with treated left temporal lobe tumor,, which may represent incipient tumor progression.2. Unchanged nonspecific subcentimeter right cerebellar hemisphere lesion.
