Pneumomediastinum Associated with Pneumonitis

The abnormal presence of air or other gases in the center of the chest and between the lungs (Mediastinum) is called pneumomediastinum, which can be spontaneous or secondary forms. Secondary occur with a specific pathologic event, such as trauma. Spontaneous pneumomediastinum (SPM)is a rare condition, without any definite etiology.The most common symptoms of the disease include chest pain, dyspnea and subcutaneous emphysema, which can usually be detected by chest radiography. Although Pneumomediastinum is a rare condition and self-limiting and usually treated, but in young people with sudden onset of chest pain, we should recognize it from other diseases. Here, we would like to report one case of a 20-year-old woman with chief complain of breath shortness,dyspnea, single coughs.
