Assess for encephalitis: intermittent seizure-like activity, catatonia, and delusions. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. Scattered areas of sulcal T2-FLAIR hyperintensity are likely attributable to supplemental oxygen. 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.
No imaging manifestations of encephalitis or other potential sources of seizures.
