A 55-year-old man with a history of bronchial asthma on steroid treatment presented with postprandial chest pain and vomiting for approximately 2 weeks. The patient had no heart burn sensation, acid regurgitation, or dyspnea. Succussion splash was heard at the left lower chest wall. Chest x-ray demonstrated an air-fluid level at the left heart border (Figure 1, arrow). Barium esophagogram confirmed the presence of bilateral esophageal diverticula at the distal portion of esophagus (Figure 2, arrows). Lung abscess can also demonstrate an air-fluid level on plain chest x-ray. This patient did not have a risk factor for lung abscess and did not show infectious signs. Thus, lung abscess was excluded initially.
