Massive Pulmonary Artery Aneurysm in a Patient with Ventricular Septal Defect: Case Report of a Rare Association

A pulmonary artery aneurysm is defined as focal dilation of the pulmonary artery beyond a diameter of 29 mm. The reported incidence is 1 in 14,000 as per the autopsy studies. A diameter of more than 55 mm is defined as a massive pulmonary artery aneurysm which is very rare. These are commonly associated with patent ductus arteriosus. No distinct features for identification and guidelines for their management warrant a detailed evaluation for etiology and close follow-up in this entity fearing fatal rupture. We present a case of a massive pulmonary artery aneurysm associated with the ventricular septal defect.
