Transient right face and hand numbness. There is a punctate focus of high T2 signal in the left pons with what may represent restricted diffusion versus artifact. There is otherwise pontine scattered cerebral white matter T2 hyperintensity bilaterally without restricted diffusion. There also appears to be a punctate focus of encephalomalacia in the left thalamus. There are bilateral choroid plexus xanthogranulomas. There is mild diffuse cerebral volume loss. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull and scalp soft tissues are grossly unremarkable. There are unchanged postoperative findings in the right orbit. There is mild scattered paranasal sinus mucosal thickening.
1. A punctate focus of high T2 signal in the left pons with what may represent restricted diffusion from an acute infarction versus chronic small vessel ischemic disease with artifact. Otherwise, pontine scattered cerebral white matter T2 hyperintensity bilaterally without restricted diffusion likely represent chronic small vessel ischemic disease, as well as a chronic lacunar infarct in the left thalamus. 2. Unchanged postoperative findings in the right orbit.
