Ischemic Stroke Presenting as the First Symptom in a Setting of Paroxysmal Nocturnal Hemoglobinuria.

Paroxysmal nocturnal hemoglobinuria is a hematological disorder characterized by hemolytic anemia, cytopenia, and thrombotic events. Venous thrombotic events are more commonly reported. An arterial thrombosis is a rare event in paroxysmal nocturnal hemoglobinuria.
