Male, 64 years old, with altered mental status and new rigidity. Image quality is reduced by motion artifact. Within this limitation, the following observations are made.No restricted diffusion is seen. No evidence of significant parenchymal edema or mass effect is detected. An area of encephalomalacia and surrounding gliosis is seen within the left occipital lobe, unchanged. A small slitlike focus of encephalomalacia is also present in the right cerebellar hemisphere compatible with chronic ischemia. A chronic lacunar infarct in the right pons is unchanged as well.No evidence of acute intracranial hemorrhage or any abnormal extra-axial fluid collection is seen. The ventricles and sulci are mildly and proportionately prominent compatible with moderate parenchymal volume loss.
1.No definite acute intracranial abnormality.2.Findings are seen compatible with chronic ischemia in the left occipital lobe, the right pons, and the right cerebellum.3.Moderate parenchymal volume loss.
