Thecontinuous diaphragm sign is a chest radiograph sign of pneumomediastinum or pneumopericardium if lucency is above the diaphragm, or of pneumoperitoneum if lucency is below the ~~diaphragm~~ diaphragm.

Normally the central portion of the diaphragm is not discretely visualised on chest radiographs as it merges with the cardiac ~~silhouette~~ silhouette. If the diaphragm can be seen ~~continuously across~~ continuously across the midline then this is highly suggestive of free gas within the mediastinum, pericardium or peritoneal cavity.
