Aneurysm of the Pulmonary Artery in Fallot’s Tetralogy

Introduction. Pulmonary artery aneurysms are a rare entity. Etiologies of these findings are multiple, but they are exceptionally associated with Fallot’s Tetralogy. In this study, we present an unusual case of an important aneurysm of the left pulmonary artery associated with Fallot’s Tetralogy disease. Case Presentation. A 30-year-old woman has been admitted for dyspnea and cyanosis. The data which had been obtained from echocardiography, cardiac catheterization, and angio-magnetic resonance imaging (MRI) suggested the existence of an important aneurysm of the left pulmonary artery associated with a regular Fallot’s disease with a pulmonic stenosis. We have noticed the presence of a small restrictive patent ductus arteriosus (PDA). Therefore, the patient was referred to surgical correction. Conclusion. Pulmonary artery aneurysms associated with Fallot’s Tetralogy are rarely reported. The natural history of these rare arterial aneurysms has to be clarified.
