Overview
Pneumomediastinum may be classified according to cause into spontaneous pneumomediastinum and secondary pneumomediastinum. Both the categories have multiple causes.
Classification
Pneumomediastinum is mainly classified according to the cause into 2 groups:[1][2]
- Spontaneous, also known as idiopathic pneumomediastinum: Predisposing factors are preexisting medical conditions such as asthma, interstitial lung disease, COPD, bronchiectasis, lung cysts, lung malignancy, excessive vomiting.
- Another cause of sponateous pneumomediastinum is use of tobacco and recreational drugs such as cocaine, marijuana, methamphetamine.
- Secondary pneumothorax:
- Iatrogenic: Endoscopic procedures, intubation/extubation, central line placement.
- Traumatic: Blunt force trauma, penetrating injury.
- Pneumomediastinum can also be classified according to the entry of air into the mediastinal cavity: Head/neck/upper respiratory tract, lower respiratory tract, lung, gastrointestinal tract, or external sources. [3]
