Spontaneous Pneumomediastinum as UncommonComplications of COVID-19 Pneumonia: 2 casereports and review of literature

Abstract

Spontaneous pneumomediastinum is a rare clinical finding and is a significant concern for
clinicians. These are two cases of fatal spontaneous pneumomediastinum among COVID-19
patients. The first patient was an 84-year-old woman who developed COVID-19 pneumonia. Her
clinical course was complicated by pneumomediastinum, and, unfortunately, she died 12 days
following the admission. The second patient was a 63-year-old man who developed a severe
pneumomediastinum and extensive subcutaneous emphysema and died 10 days after
hospitalization.
Thus, paying attention to these complications as a severity marker of COVID-19 pneumonia is
necessary.
