Thrombosed pulmonary arterial aneurysm in eisenmenger's syndrome

Abstract

FIG. 1 Chest x-ray. The right pulmonary artery (RPA) and pulmonary trunk (PT) are aneurysmal. Arrow identities a much less dilated left pulmonary artery. In his 1958 landmark article that defined the Eisenmenger syndrome, Paul Wood observed, "Dilatation of the right branch of the pulmonary artery was remarkable in only 6% of cases with ventricular septal defect,''' a radiologic observation that has withstood the test of time. We call attention to a dramatic exception in a 52-year-old male. The posteroanterior chest x-ray (Fig. 1) shows aneurysmal dilatation of the right pulmonary artery (MA) and the pulmonary trunk (PT).
