There is no restricted diffusion or abnormal enhancement. The enlarged perivascular space in the right midbrain is again seen and appears unchanged. There is no evidence of intracranial hemorrhage, mass, or acute infarct. 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, and scalp soft tissues are grossly unremarkable. There is mild maxillary sinus and frontal sinus mucosal thickening bilaterally.
