History thyroid cancer with memory difficulties, imbalance, and word-finding difficulties. There is motion artifact on several of the sequences. There is an area of encephalomalacia and gliosis involving the left parietal lobe high convexity with associated hemosiderin deposition related to prior intraparenchymal hemorrhage, which measures up to approximately 3 cm. There is slight interval increase in the extent of surrounding confluent T2 hyperintensity. There is no evidence of acute intracranial hemorrhage, mass, or acute infarct. The remaining brain parenchyma appear unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. There is a partially empty sella. The major cerebral flow voids are grossly intact. There is minimal mucosal thickening within the maxillary sinuses and a small amount of fluid within the bilateral mastoid air cells. The orbits, skull, and scalp soft tissues are grossly unremarkable. However, there is an enlarging low T1 and high T2 signal lesion in the left parotid gland.
1. Interval evolution of the prior left parietal lobe hemorrhage with increased surrounding presumed gliosis.2. An enlarging low T1 and high T2 signal lesion in the left parotid gland is incompletely characterized, but may represent a cystic neoplasm or focally dilated duct, for example. Dedicated imaging of this region may be useful.3. Nonspecific partially empty sella.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
