Memory problems. There is no evidence of intracranial hemorrhage, mass, or acute infarct. Aside from minimal nonspecific bilateral periventricular T2 hyperintensity diffusely, the signal characteristics of the brain, brainstem, cerebellum, and pituitary appear to be unremarkable. There is no abnormal intracranial enhancement. There is mild diffuse cerebral volume loss, which appears to be most pronounced in the bilateral medial temporal lobes. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull and scalp soft tissues are grossly unremarkable. There is a left lens and scleral buckle. There is mild bilateral anterior ethmoid sinus mucosal thickening. There is left mastoid fluid.
1. Mild diffuse cerebral volume loss, which appears to be most pronounced in the bilateral medial temporal lobes, may represent Alzheimer dementia. Otherwise, no evidence of intracranial hemorrhage, mass, or acute infarct. 2. Nonspecific left mastoid effusion.
