Right skull base mass. There is an enhancing dural-based mass in the right cavernous sinus region that measures up to 25 mm. There are multiple punctate foci of restricted diffusion in the bilateral cerebral hemispheres superimposed upon scattered T2 hyperintense cerebral white matter foci without restricted diffusion. There is a small area of encephalomalacia in the left paramedian pons. The ventricles and basal cisterns are unchanged 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.
1. A dural-based mass in the right cavernous sinus region likely represents a meningioma.2. Multiple punctate early subacute infarcts involving the bilateral cerebral hemispheres in a pattern most suggestive of a watershed distribution superimposed upon probable chronic small vessel white matter disease and a left pons chronic infarct.
