Herein are reported the cases of two women: one with pulmonary fibrosis, of unknown etiology, resembling the Hamman-Rich syndrome; the other with cor pulmonale secondary to an unsuspected lipoid pneumonia. In both cases, angiocardiography, by visualizing the cardiovascular structures, demonstrated the enlarged pulmonary artery and branches, suggested the diagnosis of cor pulmonale, and excluded the diagnosis of hilar and mediastinal neoplasm.1

Report of Cases 

Case 1.—  A 43-year-old woman was admitted to the hospital on Sept 8, 1964, with complaint of dyspnea. She had been in good health until two years prior to admission when a routine roentgenogram of the chest showed bilateral upper-lobe pulmonary infiltrates. Although acidfast bacilli were not found in the sputum, she was treated with antituberculous drugs for five months. Ten months prior to admission she was exposed
