Lung5
- In the case of scuba and surface supplied divers, the diver breathes gas at ambient pressure, and if this is not able to escape freely during ascent, the pressure difference will cause it to expand, and may rupture the lung tissues (pulmonary barotrauma), and escape to a variety of places, one of which can be the mediastinum. (wikipedia.org)
- Most often, it occurs when air leaks from any part of the lung or airways into the mediastinum. (medlineplus.gov)
- The generally accepted explanation for the development of pneumomediastinum is that free air tracks from ruptured alveoli along peribronchial vascular sheaths toward the hilum of the lung. (medscape.com)
- Possible lung collapse, due to build up of air in the mediastinum and subsequent pervading of the space around the lungs. (hxbenefit.com)

Abnormal presence of air2
- Pneumomediastinum (from Greek pneuma - "air", also known as mediastinal emphysema) is pneumatosis (abnormal presence of air or other gas) in the mediastinum, the central part of the chest cavity. (wikipedia.org)
- Pneumomediastinum is the medical term for the abnormal presence of air within the mediastinum. (medicalnewstoday.com)
Airways2
- It is defined as free air or gas contained within the mediastinum, which almost invariably originates from the alveolar space or the conducting airways. (medscape.com)
- This is a rare disorder occurring due to leakage of gas or air from the lungs or airways and its subsequent entry into the mediastinum. (hxbenefit.com)
Conservatively2
- Pneumomediastinum with angel wing sign Pneumomediastinum as seen on ultrasound The tissues in the mediastinum will slowly resorb the air in the cavity so most pneumomediastinums are treated conservatively. (wikipedia.org)
- Clinical and radiological findings led to the diagnosis of pneumomediastinum, which was treated conservatively. (who.int)
Trachea1
- There is a prominent air density outline of the trachea on the lateral view (arrow points to a double outline of the tracheal air column) which is again suggestive of pneumomediastinum. (hawaii.edu)
Tissues2
- Most cases of this disease do not require any treatment as the tissues present in the mediastinum, over a period of time, slowly reabsorb the air in cavity. (hxbenefit.com)
- The outcome of the disease is generally good as the air in the mediastinum is frequently absorbed by the surrounding tissues. (hxbenefit.com)
Diagnose2
- To diagnose pneumomediastinum, a doctor will take a medical history and perform a physical examination. (medicalnewstoday.com)
- Chest computed tomography (CT) may be used to diagnose pneumomediastinum not visualized on chest radiography. (medscape.com)
Diagnosis1
- The diagnosis can be confirmed via chest X-ray showing a radiolucent outline around the heart and mediastinum or via CT scanning of the thorax. (wikipedia.org)
Mediastinal1
- Rarely, tension pneumomediastinum has been reported in which elevated mediastinal pressure leads to diminished cardiac output because of direct cardiac compression or reduced venous return. (medscape.com)
Symptoms2
- Pneumomediastinum may also present with symptoms mimicking cardiac tamponade as a result of the increased intrapulmonary pressure on venous flow to the heart. (wikipedia.org)
- In some cases , pneumomediastinum may not cause any symptoms. (medicalnewstoday.com)
Occur due1
- This may occur due to uncommon buildup of air around the center of the chest that exerts great pressure on the heart and its blood vessels. (hxbenefit.com)
Neck1
