Pulmonary pseudofibrosis and pseudomass lesions

Abstract

Abnormal size and/or number of the pulmonary and bronchial vessels and lymphatics may mimic pulmonary parenchymal lesions (pseudofibrosis). Abnormalities of the central pulmonary artery, pulmonary vein, thoracic aorta, and brachiocephalic branches may mimic intrathoracic mass lesions (pseudomass lesions). Radiologists should interpret these radiographic findings in the light of other accompanying radiographic findings and the clinical presentation.
