Image Challenge: Tramatic Pneumothorax

71-year-old male with chronic heavy alcohol use was admitted to the hospital for a left femoral neck fracture from a fall while he was intoxicated. He underwent open reduction and internal fixation, but his post-operative course was complicated by aspiration pneumonia and delirium. A Nasogastric Tube (NGT) was required for feeding which led to immediate worsening of his respiratory status. A follow up chest X-ray (CXR) was obtained (Figure 1). The patient has provided informed consent.
