Overview
Laboratory Findings
Significant cases of subcutaneous emphysema are easy to diagnose because of the characteristic signs of the condition.[1] In some cases, the signs are subtle, making diagnosis more difficult.[2] Medical imaging is used to diagnose the condition or confirm a diagnosis made using clinical signs. 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.[3] It can also and reduce the effectiveness of chest ultrasound.[4] On the other hand, since subcutaneous emphysema may become apparent in chest X-rays before a pneumothorax does, its presence may be used to infer that of the latter injury.[2]
