Male, 81 years old, rapid decline in cognition in patient with baseline dementia and new gait disturbance. Relatively mild scattered periventricular and subcortical T2 hyperintensities are seen, a nonspecific finding which may reflect chronic microvascular disease. No restricted diffusion is seen to suggest acute ischemia. No evidence of parenchymal edema or mass effect is detected.The ventricles and sulci are diffusely prominent compatible with volume loss. The morphology of the ventricular system is otherwise unremarkable. No evidence of intracranial of cranial hemorrhage or any abnormal extra fluid collection is seen.
1. Chronic microvascular ischemic disease and generalized parenchymal volume loss.2. No other specific findings to account for the patient's symptoms.
