An ischemic stroke during intravenous recombinant tissue plasminogen activator infusion for evolving myocardial infarction.

A 56-year-old man without a previous history of stroke received intravenous recombinant tissue plasminogen activator (tPA) for an evolving myocardial infarction. During the infusion, the patient developed aphasia and right hemiparesis. The CT and MRI confirmed an ischemic stroke without evidence of hemorrhage. Although the cerebral hemorrhage after tPA infusion is relatively more common, in rare cases, tPA infusion may result in fragmentation of a cardiac thrombus resulting in an ischemic cerebral stroke.
