There is not a systematic review about double contour in thoracic radiography in the literature. We present a 64-year-old male patient with bilateral double density sign in chest X-ray. The case was admitted with complaints of syncope to the emergency department. Arterial blood gas analysis was consistent with respiratory failure. A mucoid impac-tion in the right lower lobe was aspirated during bronchos-copy. Chest computerized tomography demonstrated a huge diaphragmatic hernia and intrathoracic stomach in the posterior mediastinum. The patient was treated with intra-venous diazepam for delirium tremens. All related papers were reviewed with Google and Pubmed search using keywords “double contour sign” or “double density sign”. In conclusion, pulmonary, cardiac, and retrocardiac medi-astinal diseases can cause double density sign.
