bilateral basal ganglia and external capsule. hospital course: mr. was admitted to the with right hemiparesis and resolved aphasia with history of a transient ischemic attack eight years previously. he had a urinary tract infection for which he was started on levofloxacin. he was admitted to telemetry, to have close neurological assessments and an mri with stroke protocol. an mri was performed and did show an infarct in the left corona radiant. echocardiogram which did show some mild left atrial dilatation, but no emboli was visualized. on , he also underwent carotid ultrasound in the vascular laboratory bilaterally. this did show a very tight left internal carotid artery narrowing greater than 95% and mild on the right internal carotid artery with narrowing of less than 40%. on ,
