Improved aeration of both lung bases with resolved opacities in the right base and trace linear opacity in the left base, likely representing atelectasis. Mild blunting of the left costophrenic angle may indicate trace residual effusion or pleural thickening. No obvious effusion on the right and no pneumothorax are present.
