Possible transient global amnesia. There is a punctate focus of restricted diffusion in the right hippocampus, with apparent high T2 signal. The rest of the brain parenchyma, brainstem, and cerebellum appear unremarkable. There is no evidence of intracranial hemorrhage or tumor. There is no abnormal intracranial enhancement. 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. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
