Atypical presentation of unilateral pulmonary artery agenesis diagnosed postpartum

A 27-year-old woman developed a cough, shortness of breath, and symptoms mimicking pregnancy complications 6 days after childbirth. Unilateral pulmonary artery agenesis (UAPA), a rare congenital condition, was diagnosed through a chest CT scan. This case highlights the variable presentation of UAPA, even in adults, and the challenges of diagnosis during the postpartum period. Early diagnosis and management are critical for improving pregnancy outcomes in women with UAPA.
