Abstract

Pulmonary artery pseudoaneurysm (PAP) is a rare complication of septic pneumonia. It is potentially fatal because of the risk of massive hemoptysis. Treatment of PAP involving massive hemoptysis is by embolization or surgery. However, the progression of PAP after embolization has not been reported. A 59-year-old male who was recovering from septic pneumonia experienced massive hemoptysis. Computed tomography (CT) revealed PAP of the right pulmonary artery with surrounding consolidation, suggesting active hemorrhage. The patient was successfully treated with embolization of the right pulmonary artery. During outpatient follow-up, the amount of radiopaque embolized material gradually decreased on chest radiography. At 14 months after embolization, both the PAP and embolized material had disappeared on chest CT.
