Cardiac and mediastinal contours are likely unchanged; however, patient rotation to the right may affect the assessment. Streaky linear opacities at the medial left lung base may suggest atelectasis, but aspiration or early pneumonia cannot be excluded. There is no evidence of pulmonary edema, pleural effusions, or pneumothorax.
Simple pleural effusion (Absent) Edema (Absent) Atelectasis (Uncertain) Aspiration (Uncertain) Simple pneumothorax (Absent) Pneumonia (Uncertain)
