Emphysematous gastritis is a cause of gastric emphysema, and specifically refers to infectious gastritis. It is an uncommon entity with a high mortality rate. In this condition, microorganisms (e.g. Escherichia coli, Clostridium perfringens) produce the gas, which is identified within the stomach wall.
Imaging appearances are similar and essentially indistinguishable to other causes of gas within the stomach wall; please refer to gastric emphysema.
