Lesions on head CT. There are scattered bilateral cerebral hemisphere punctate foci of T2 hyperintensity with mildly restricted diffusion in a watershed distribution. A few lesions in the left occipital lobe cortical region demonstrate mild enhancement and susceptibility effect. There is no evidence of large intracranial hemorrhage or mass. 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. There is an unchanged polypoid lesion in the anterior left nasal cavity and a small retention cyst in the right maxillary sinuses. The orbits and skull are grossly unremarkable. There is a nonspecific subcentimeter left frontal scalp lesion.
