64 years, Male, right hemiparesis and dysarthria.. Please note examination is motion degraded and limited to diffusion-weighted, sagittal T1, and axial T2-weighted sequences. There is restricted diffusion in the left pons consistent with acute infarct. Previously seen infarct involving the right aspect of the pons on prior MRI demonstrates evolution with residual T2 hyperintensity in this region.Volume loss compatible with chronic infarct in the left posterior inferior cerebellar artery territory is again seen. Patchy areas of T2 hyperintensity are seen in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with chronic small vessel ischemic disease. No evidence of intracranial mass effect, midline shift, or herniation. Ventricles remain normal in size.
Patient could not tolerate the full study and limited sequences were obtained. There is evidence of acute infarct involving the left aspect of the pons and evolution of the infarct involving the right aspect of the pons seen on recent MRI from 6/23/2016. Chronic left PICA territory infarct also again seen.
