Idiopathic pulmonary artery aneurysm: Digital subtraction pulmonary angiography grossly underestimates the size of the aneurysm

Aneurysms of the Pulmonary Artery

“…[34][35][36] Greene and Baldwin 37 have defined 4 pathological criteria for an idiopathic PAA: simple dilatation of the pulmonary trunk with or without involvement of the rest of the arterial tree, the absence of intracardiac or extracardiac shunts, the absence of chronic cardiac or pulmonary disease, and the absence of arterial disease such as syphilis or more than minimal atheromatosis or arteriosclerosis of the pulmonary vascular tree.…”

“…9,20,34 Clinical symptoms include dyspnea, chest pain, hoarseness, palpitation, and syncopal episodes. 6,14,20,21,[34][35][36] Bronchus compression by a large PAA may be responsible for cyanosis, cough, and increasing dyspnea, pneumonia, fever, and bronchiectasis. 20,21,28,34,35,39 In addition, patients with PAA have a high incidence of pulmonary emboli.…”

“…21,39 Hemoptysis has been described as a possible symptom and might be a warning sign for imminent aneurysm rupture. 34,35 In case of rupture, lethal hemostasis, asphyxiation, exsanguination, and sudden death have been described. 40 Among all reported cases, one third of the patients died as a result of rupture, which underlines the fact that not all PAAs progress to the rupture state.…”

Traumatic Arterio-Venous Pulmonary Pseudoaneurism

“…Spiral CT also has the ability of multiplanar reconstruction that can provide very useful information to the surgeon for planning surgery. For optimal imaging in the workup, echocardiography and MRI should be included [12].…”
