A 26-YEAR-OLD MAN came into the emergency department for treatment of vomiting, and pain in his abdomen and right shoulder. His vital signs were normal, with the exception of his heart rate, which was 109 bpm. His oxygen saturation was 96% on room air. The patient, a smoker, did not complain of any difficulty breathing, despite having diminished breath sounds over the left lung fields and absent breath sounds over the right. The rest of the exam was normal.
The patient’s initial blood work was within normal limits. We ordered a chest x-ray (FIGURE 1) and a chest computed tomography (CT) scan to further assess his decreased breath sounds.
