History of glioma status post surgery. MRI for RT treatment planning. Recent postoperative findings related to biopsy of an irregularly rim-enhancing mass centered in the right temporal stem and posterior right insula that measures up to approximately 3 cm, with multiple adjacent smaller peripherally-enhancing nodules and extensive surrounding edema involving right thalamus, right middle cerebral peduncle, right basal ganglia, and right parietal lobe. There are T1 hyperintense subacute blood products within the central portion of the otherwise necrotic tumor. There are areas of T2 hyperintensity in the right parietal lobe white matter without corresponding enhancement. There is effacement of the temporal horn of the right lateral ventricle and most of the third ventricle, but mild prominence of the bodies of the lateral ventricles. There is mild midline shift to the left, but no herniation. There is no evidence of acute infarct. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There are retention cysts in the left maxillary sinuses.
Recent postoperative findings related to biopsy of the dominant mass centered in the right temporal stem and posterior right insula, with multiple satellite lesions, which are compatible with a high grade glial neoplasm.
