Deformity of the left chest wall with associated pleural thickening. A likely small loculated hydropneumothorax is seen in the left mid zone. Blunting of the left costophrenic angle suggests pleural thickening and/or pleural fluid. An ovoid opacity in the left upper lung, not seen on prior films, may represent loculated fluid in the oblique fissure.
