Glioblastoma: behavioral changes and confusion. There are postoperative findings related to left anterior temporal lobectomy. There is persistent confluent T2 hyperintensity and swelling in the remaining portions of the left temporal lobe, with an enhancing component that measures up to approximately 15 mm. Overall, this appears similar in extent as on the prior scan. There is no evidence of acute intracranial hemorrhage or acute infarct. There is also unchanged patchy T2 hyperintensity within the left periatrial white matter and minimal punctate T2 hyperintensity in the right posterior centrum semiovale. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are unchanged. There are retention cysts in the bilateral nasopharyngeal recesses. There is fluid within the bilateral mastoid air cells.
