[Giant aneurysm of the pulmonary artery: a case report].

Pulmonary artery aneurysm is a rare condition accounting for less than 1% of all intra thoracic aneurysms. This paper reports a case of giant aneurysm of the trunk and branches of the pulmonary artery, which was discovered incidentally on a computed tomography angiogram in a 48-year-old man with a past history of pulmonary tuberculosis. Besides the aneurysm there was dilation of the pulmonary annulus with massive pulmonary regurgitation, a tight mitral stenosis and sequelae of pleural and pulmonary tuberculosis. The patient is being followed-up with medical treatment and has been stable clinically for the last ten months.
