Congenital unilateral agenesis of pulmonary artery is a rare anomaly and it usually occurs in association with other cardiac anomaly such as tetralogy of Fallot. Since most patients affected by this defect without associated congenital cardiac
anomaly
or pulmonary infection are asymptomatic, the clinical diagnosis of this anomaly is recognized by a characteristic pattern in chest roentgenogram taken as a routine checking; the findings on chest film sonsists of cardiac and mediastinal
displacement,
absence of the pulmonary arterial shadow, smaller hemithorax, and elevationof the hemidiaphragm, all on the affected side.
We experienced right pulmonary artery agenesis in a 48 year-old male, who complained of massive hemoptysis, and it was diagnosed by digital subtraction pulmonary arteriogram and perfusion scan, and treated by right middle and lower lobe
bi-lobectomy,
and we report this case with the review of relevant literatures.
