Reason: Alzheimer's disease No abnormal signal is seen on the T2, FLAIR or diffusion weighted images. There is no evidence of intracranial hemorrhage, mass or edema. Since the prior exam, there has been mild interval increase in symmetric dilatation of the occipital and temporal horns of the lateral ventricles bilaterally as well as the third ventricle. The cortical sulci of the medial temporal lobes appear more prominent, predominantly in the region of the sylvian fissure and hippocampus, consistent with some interval volume loss.
Progressive symmetric bi-temporal lobe atrophy, consistent with reported history of Alzheimer's dementia.
