    INPUT: Two views of the chest were obtained . Upper lobe linear opacities and associated right apical pleural thickening is unchanged from multiple previous examinations and likely reflects post-treatment changes . New blunting of the right costophrenic sulcus may reflect pleural thickening or small pleural effusion without associated parenchymal opacity . The left lung is well aerated . No pneumothorax is seen . Heart is normal in size with calcifications in the left mediastinum , unchanged from the previous CT . Degenerative changes are seen of both shoulders with intra-articular body seen in the right shoulder .
