Male, 56 years old, with encephalopathy. Image quality is degraded by motion artifact. Within this limitation, the following observations are made.Prominence of the ventricular system is again seen, out of proportion to the caliber of the sulci. A thin rim of T2 hyperintensity is seen along the ventricular margins.There may be a few additional scattered small foci of T2 hyperintensity. No evidence of restricted diffusion or significant parenchymal edema is seen. No abnormal extra-axial fluid collection or acute intracranial hemorrhage is detected.The left mastoid air cells are opacified.
1.Prominence of the ventricles out of proportion to the caliber of the sulci is again seen. This could reflect a communicating hydrocephalus versus an atypical central pattern of parenchymal volume loss.2.No other significant or acute intracranial findings are seen.
