    INPUT: There are relatively low lung volumes . Increased prominence of the soft tissue along the lower right peritracheal region and right hilar region is nonspecific , but could be due to lymphadenopathy versus prominent vascular structures or mediastinal fat . Right mid lung atelectasis / scarring is seen . There is no definite focal consolidation . No pleural effusion or pneumothorax is seen . The cardiac silhouette is top - normal to mildly enlarged . The aortic knob is calcified . Degenerative changes seen along the thoracic spine without loss of vertebral body height .
