Spontaneous pneumomediastinum as a complication of COVID-19.

In December 2019, an atypical form of severe pneumonia emerged in Wuhan in China's Hubei province, which in February 2020 was named COVID-19. The disease may have features of interstitial pneumonia and severe respiratory failure requiring intensive oxygen therapy. Spontaneous pneumomediastinum is a rare pathological condition with air in the mediastinum outside the trachea, oesophagus and bronchi.
