There is an extensive area of high signal intensity on DWI and low signal on ADC in the left cerebral hemisphere involving the cortical grey and deep white matter of the frontoparietal lobes and the basal ganglia representing the middle cerebral artery territory. T1W showed isointense signal with obliteration of the Sylvian fissure due to edema, there is subtle increased signal intensity on T2/FLAIR, no evidence of hemorrhagic changes is noted on GRE.
The right cerebral parenchyma shows focal areas of chronic infarction in the deep white matter involving the corona radiata and centrum semiovale.
