On a chest radiograph, subcutaneous<unk>  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. It can also and reduce the effectiveness of chest ultrasound.  On the other hand, since subcutaneous<unk>  may become apparent in chest X-rays before a pneumothorax does, its presence may be used to infer that of the latter injury.
