Deformity of the left chest wall with associated pleural thickening. A likely small loculated hydropneumothorax is again apparent in the left mid zone. Blunting of the left costophrenic angle is compatible with pleural thickening and/or pleural fluid. An ovoid opacity is seen in the left upper lung, not apparent on the prior film, which may represent loculated fluid in the oblique fissure.
Hydropneumothorax (Uncertain) Pleural scarring (Present)
