A Case of Covid-19 With No Pulmonary Involvement; But With Mediastinal and Subcutaneous Emphysema

Spontaneous pneumomediastinum (spm) is a rare clinical entity. in the normal population, it is more likely to occur in people with conditions including chronic obstructive pulmonary diseases and asthma. in the context of covid-19 few cases of spm have been reported which most of them were patients with severe lung parenchymal inflammation or patients under mechanical ventilation. in this case, we report a young male with a history of minor childhood asthma who presented with acute dyspnea, forceful coughs, and subcutaneous emphysema. chest computed tomography had no clues for covid-19, however, pneumomediastinum and subcutaneous emphysema were obvious. he was primarily diagnosed with acute asthma exacerbation causing spm but eventually, he tested positive for sars-cov-2, therefore, he underwent the standard treatment for covid-19 and the spm was managed conservatively. finally, after 12 days of hospitalization, he was discharged in favorable clinical condition.
