Male, 19 years old. History of DNET status post resection 06/2015. Followup. There are again postoperative changes of left parietal craniotomy and resection of a mass in the left precentral gyrus. The small resection cavity appears unchanged, with minimal chronic hemosiderin staining and mild T2 hyperintensity at the rim. There is no abnormal parenchymal or leptomeningeal enhancement in the region of the resection cavity or elsewhere. No new lesions are identified. There is no evidence of acute intracranial hemorrhage or acute infarct. The brain parenchyma otherwise appears unremarkable. The midline structures and craniocervical junction are within normal limits. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There is mild scattered ethmoid air cell opacification. Otherwise, the orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Expected findings related to resection of a left frontal lobe lesion, without evidence of recurrent tumor or other acute abnormality.
