Pulmonary Artery Pseudoaneurysms: Clinical Features and CT Findings

Abstract

PAPs showed a strong predilection for the peripheral pulmonary arteries. Multiplicity of PAPs can be seen in the settings of endocarditis and pulmonary metastatic disease. Most PAPs were not associated with a ground-glass halo. PAPs can be lethal but were often not suspected clinically and were underreported by radiologists.
