Preschooler with cough, fever, shortness of breath

CXR and CT of pleural empyema
CXR PA and lateral shows complete opacification of the left hemithorax causing tracheal and mediastinal shift to the right, which is seen on the axial CT with contrast of the chest to be due to a large pleural fluid collection with an enhancing pleura causing near complete left lung atelectasis.

The diagnosis was bacterial pneumonia with a pleural empyema.
