New ischemic stroke: vertigo. There is persistent high T2 signal in the right precentral gyrus and inferior frontal gyrus with new punctate foci of restricted diffusion. There is also mild gyriform susceptibility effect in the right precentral gyrus, which may represent microhemorrhages or cortical laminar necrosis. There is unchanged mild periventricular white matter T2 hyperintensity. The ventricles are unchanged in size and configuration. There is an unchanged subcentimeter arachnoid cyst in the anterior left circular sulcus. There is no midline shift or herniation. There are left ethmoid sinus secretions. The skull and scalp soft tissues are unremarkable.
Late subacute to early chronic right precentral and inferior frontal gyri infarcts with superimposed punctate foci of acute infarction, but no midline shift or gross intracranial hemorrhage.Discussed with Dr. Guan at 10:10 AM on 4/6/15.
