On a chest [[radiograph]], subcutaneous emphysema may be seen as radiolucent striations in the pattern expected from the [[pectoralis major]] muscle group. Air in the subcutaneous tissues may interfere with [[radiography]] of the chest, potentially obscuring serious conditions such as pneumothorax.<ref name="Criner02">
