Stable asymmetric appearance of the pulmonary parenchyma, with reduced right lung volume and diffuse reticular opacities consistent with fibrosis. Interval development of opacity at the left lung base, with blunting of the left costophrenic angle which may represent scarring, a left pleural effusion, or pleural thickening.
