Abstract Background Isolated unilateral absence of one pulmonary artery (IUAPA) is a rare malformation and a rare cause of hemoptysis. It occurs due to malformation of the sixth aortic arch during embryogenesis. This condition has variable presentations like dyspnoea, reduced exercise tolerance, chest pain, pleural effusion, recurrent bronchopneumonia, pulmonary hypertension, and haemoptysis can be asymptomatic. Case Presentation We describe a case of a 34-year-old female presenting with recent onset hemoptysis associated with mild dyspnoea and cough. Chest Radiograph revealed unilateral hyperlucent lung field which was later diagnosed as Isolated unilateral absence of pulmonary artery on high resolution computed tomography of chest with angiography. Conclusion Absent pulmonary artery should be considered as an important differential in cases presenting with hemoptysis. This case emphasises the significance of combining computed tomography with pulmonary angiography to accurately evaluate and define congenital lung abnormalities.
