    INPUT: Frontal and lateral views of the chest are obtained . There is a moderate left pneumothorax . Lucency along the left mediastinum / pericardial region could be due to the pneumothorax ; however , a pneumomediastinum is not excluded . There is no shift of the mediastinum . Left - sided rib interspaces appear widened as compared to the right , although this could relate to patient 's scoliosis . Otherwise , the lungs are hyperinflated . There is left base atelectasis , small left pleural effusion not excluded . The cardiac silhouette is not enlarged . Mediastinal contours are unremarkable . There is a minimally displaced fracture of the posterolateral left sixth rib . Mild bi-apical pleural thickening is seen .
    OUTPUT:
    
1 . Moderate left pneumothorax . No mediastinal shift ; however , the left - sided rib interspaces are wide as compared to the right side and while this could relate to patient 's scoliosis , tension is not excluded . Lucency along the left heart border and left mediastinum may relate to pneumothorax , although pneumomediastinum can have the same appearance . 2 . Left base opacity may be due to atelectasis , although a small left pleural effusion is not excluded . 3 . Minimally displaced left posterolateral sixth rib fracture . The above findings were discussed with Dr . ___ at 8 :55 p .m . on ___ , 6 minutes after discovery .
