Background
Ectopic gas is defined as the presence of gas in abnormal locations.Ectopic gas in the mediastinum, subperitoneal abdomen, and superficial soft tissues is concerning and can be seen in the setting of trauma, iatrogenic injuries, infection, and inflammation.As a result of fascial interconnectivity and pressure differences between compartments, gas can dissect distant from its source.Based on the embryologic development, an anatomical continuum exists between the spaces allowing air/gas to spread along them.
