We report a case of isolated unilateral absence of the pulmonary artery, a rare congenital anomaly, in a woman with exertional dyspnoea. The chest radiograph appearances of this anomaly are often mistaken for other conditions, such as Swyer-James-MacLeod's syndrome or thromboembolic disease. The interpretation of chest radiograph findings in order to differentiate isolated unilateral absence of the pulmonary artery from other conditions is discussed, along with the appropriate use of ancillary imaging techniques.
