A case of paroxysmal nocturnal hemoglobinuria presenting with intra-abdominal bleeding due to splenic rupture, developing renal infarct

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disorder characterized by intravascular hemolysis, hemoglobinuria, and thrombosis. Thrombotic attacks are life threatening and are responsible for nearly 50% of PNH-related deaths. Compared with thrombotic events, bleeding related to thrombocytopenia in PNH is quite rare. This report describes an atypical clinical presentation with problems in the diagnosis and management of a woman who presented with a splenic infarct followed by massive intra-abdominal bleeding due to splenic rupture. She also developed a renal infarct during hospitalization after diagnosis.
