“…When summarizing the reported cases of PAA in the elderly (>60 years old), one-third of the patients with PAA had lung cancer (1,8,12,(17)(18)(19)(20)(21)(22)(23). Although the mechanism underlying the association between PAA and lung cancer remains unclear, structural developmental abnormalities in the hypoperfused lung and DNA damage caused by chronic hypoxia are speculated to potentiate the development of cancer (12).…”

An Adult Case of Unilateral Left Pulmonary Artery Agenesis Presenting with Hemoptysis

et al. 2023

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.
