Pneumothorax, Pneumomediastinum, and Subcutaneous Emphysema as Complications of COVID-19 Infection: A Case Series

The novel coronavirus infection is a global health concern in 2020. Computerized tomography (CT) scan has an important role in diagnosis and follow-up with the course of the disease. The most common radiologic findings in patients are bilateral peripheral patchy ground-glass opacities and consolidations. Although in a few cases, as we reported, we encountered some rare manifestations such as pneumothorax, pneumomediastinum, and subcutaneous emphysema, which imply distinct concerns about the management and outcome of the disease. Pulmonary interstitial emphysema develops due to an increase in alveolar pressure or because of alveolar rupture, secondary to alveolar membrane damage by the virus and proceed to such a complication. Therefore, it is crucial to be aware of the complications of novel coronavirus infection in the deterioration of the disease.
