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. Trace right maxillary mucosal thickening. The orbits, skull, and scalp soft tissues are grossly unremarkable.MRA:The intracranial internal carotid arteries are normal in course and caliber. The middle and anterior cerebral arteries are unremarkable. The vertebral arteries, basilar artery, and right cerebral arteries are normal in course and caliber.
