Pulmonary Artery Hypertension Masquerading as Hilar Mass

This is a case of a 68-year-old man who came with complaints of chronic dry refractory cough of 3-month duration. He is a known case of atrial septal defect (ASD). Chest radiograph done showed prominent convex pulmonary bay with right hilar mass. Contrast-enhanced computed tomography (CECT) thorax was done. The mass-like lesion was found to be an enlarged and dilated pulmonary artery. The refractory cough was due to compression of larger airways by pulmonary trunk.
