Glioblastoma treated with RT/TMZ+TMZ. There are post-treatment findings in the left frontal lobe. There is unchanged confluent T2 hyperintensity surrounding the left frontal lobe resection cavity and elsewhere in the right cerebral white matter. A focus of enhancement along the posterior margin of the resection cavity is slightly less prominent. A punctate focus of enhancement in the anterior right superior frontal gyrus is also less conspicuous. There is no evidence of 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, and scalp soft tissues are unchanged. There is a left maxillary sinus retention cyst.
