Tętniak tętnicy płucnej imitujący rozwarstwienie tętnicy płucnej wykryty za pomocą obrazowania multimodalnego

An idiopathic pulmonary artery aneurysm (PAA) is an uncommon lesion, and is defined when the diameter of the pulmonary trunk is greater than 30 mm in the absence of cardiac or pulmonary etiologies. Idiopathic PAA is generally asymptomatic and has an increased risk for dissection or rupture of the aneurysm. We herein demonstrate two- and three-dimensional echocardiographic and computerised tomographic angiography features of an idiopathic pulmonary aneurysm mimicking a pulmonary artery dissection
