Subcutaneous emphysema

Considerations:
Subcutaneous emphysema is a rare finding and generally related to the inadvertent introduction of air into tissues (such as through a pneumomediastinum). It can also occur from the production of gas within a tissue by infection such as in gas gangrene . It can occur in the bowel wall from infection with Clostridia difficile as is seen in necrotizing enterocolitis in the newborn.

Subcutaneous emphysema can often be seen as a smooth bulging of the skin. Palpation , or feeling of the skin, produces an unusual crackling sensation as the gas is pushed through the tissue.

Common Causes:
