Left Pulmonary Agenesis Showing Extraordinary Chest X-Ray Findings

摘要

An 80-year-old woman was admitted to a regional hospital owing to a duodenal ulcer. Although her ulcer improved after treatment, her symptoms of Alzheimer's disease worsened, and she was transferred to our hospital. On admission, her chest X-ray findings revealed a mediastinal shift to the left side and a small left lung (Figure 1A). The chest computed tomography findings revealed her left lung to be absent and that her right lung had entered the left thoracic cavity (Figures 1B-1D). She had not received any thoracic surgery in the past. She had not previously been diagnosed as having pulmonary agenesis or any other malformations. She did not have any particular symptoms.
