Abstract:
Pulmonary artery agenesis (PAA) is a rare congenital vascular anomaly usually diagnosed during infancy. We herein report a 67-year-old man with PAA manifesting as massive hemoptysis. Contrast-enhanced computed tomography of the chest revealed the diagnosis of PAA, which we speculated to have resulted in the present event. Detailed angiography provided more accurate information on the pulmonary vasculature and collateral circulation, which helped us plan tailored treatment. Although very rare, we must consider the possibility of PAA in adults with unexplained hemoptysis.

Overview of Pulmonary Circulation
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...
