was confirmed pathologically. Our patient had no underlying predisposing factors for pulmonary hemorrhage apart from heart failure. We conclude that pulmonary hemorrhage is a rare but important complication of thrombolytic therapy. Underlying pulmonary disease, pulmonary artery catheterization, or pulmonary edema may predispose to this event. Pulmonary hemorrhage should be considered in the differential diagnosis of new infiltrates on chest radiography or falling hemoglobin levels in patients who received thrombolytic therapy. Awareness of the possibility of such a side effect, early recognition, and treatment may prevent significant morbidity and mortality.
