Spontaneous pneumomediastinum secondary to COVID-19 in Iran: A case series study

BACKGROUND: Pneumomediastinum is defined as open-air in the mediastinum. Spontaneous pneumomediastinum (SPM) occurs when air leaks into the surrounding vascular sheath through small alveolar ruptures. CASE REPORT: We want to introduce 4 different cases with different outcomes. The first case was a 60-year-old man with a history of psychological disorders, the second case was a 41-year-old man with a history of hypertension (HTN) and asthma, the third case was a 50-year-old heavy smoker with no history of an underlying disease, and the fourth case was a 60-year-old man with a history of schizophrenia. They suddenly developed an exacerbation of cough, dyspnea, chest pain, and a severe decrease in oxygen saturation during hospitalization. Antibiotic therapy, corticosteroids, and high-dose oxygen therapy were administered to the patients. One of these patients died. CONCLUSION: All patients can potentially be at risk for this complication and have a good prognosis if diagnosed early and treated properly overall.
