Patient with history of seizure, follow up right mesial temporal abnormal T2 signal. There is now volume loss of the right hippocampus, with residual T2 hyperintensity. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is a right maxillary sinus polyp or mucous retention cyst. There are also small nasopharyngeal retention cysts.
Interval volume loss in the right hippocampus, which is most suggestive of mesial temporal sclerosis, perhaps as a sequela of limbic encephalitis.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
