Abstract

|
|
|
Pulmonary artery pseudoaneurysm (PAP) is a very rare vascular abnormality and is often caused at least in part by infection. While Mycobacterium tuberculosis is a relatively common cause of PAP, it can also result from a lung abscess. Aneurysm rupture resulting in massive hemoptysis is potentially fatal, with death caused by aspiration of blood and consequent asphyxiation. We admitted a 55-year-old man with massive hemoptysis. He had been treated with intravenous antibiotics for three weeks after diagnosing a lung abscess. Contrast-enhanced chest computed tomography revealed a pseudoaneurysm inside the abscess. Diagnostic catheter pulmonary angiography confirmed the diagnosis of pseudoaneurysm of the pulmonary artery. Embolization successfully controlled the airway bleeding. However, the patient died of acute respiratory failure on the seventh hospital day. When hemoptysis is due to sustained inflammation, such as a lung abscess, bleeding from the pulmonary artery should be considered.
