Imaging findings of the patient. Axial diffusion-weighted imaging (DWI) of brain MRI reveals several small acute infarcts involving the frontal and parietal lobes, right corona radiata and dorsal putamen shown with bright signal in the distribution of the right MCA territory and in the territories of the posterior watershed area compatible with the area of the apparent diffusion coefficient (ADC) reduction (a-d). The 3D time-offlight (TOF) MR angiography demonstrates abrupt disruption in mid-segment of M1 of right MCA (e). Long TR sequences demonstrate high signal abnormality centered in the right temporal, occipital, and middle frontal lobes suggesting old ischemia or infarct on the right cerebral hemisphere (f-h).
