 No diffusion-weighted abnormalities are identified. There are no masses, mass effect, or midline shift. There is no abnormal enhancement within the brain. Periventricular and subcortical white matter hypoattenuation likely represents chronic small vessel ischemic disease.

There is a small mucous retention cyst in the right sphenoid sinus. The mastoid air cells are clear.
