A 38-year-old male, a smoker (28 pack years), was referred to our Institute with history of chronic dyspnoea having poor response to inhaled bronchodilators. Erect chest radiographs were performed and the posteroanterior view is shown (Figure 1).

Figure 1. Chest radiograph posteroanterior view, showing lucency (white arrow) under right hemidiaphragm consistent with loop of colon interposed between right hemidiaphragm and liver. Over left side, air-fluid level in stomach below left hemidiaphragm is distinctly visible (black arrow).


What is the diagnosis?
