Plasminogen Activator Inhibitor-1 4G/5G Polymorphism Presenting as Recurrent Ischemic Stroke: The Microthrombi Shower.

Certain clinical scenarios should alert a physician to take a deeper look into causative pathological processes. This was evident in the case of a 41-year-old man who presented for recurrent micro thromboembolic strokes, which is atypical for the patient's age. Our desire to explain the pathological process led to the rare finding of a plasminogen activator inhibitor-1 polymorphism, which has been associated with an increased risk of cerebrovascular thrombosis.
