Mediastinal Emphysema, Giant Bulla, and PneumothoraxDeveloped during the Course of COVID-19 Pneumonia

ABSTRACT

The coronavirus disease 2019 (COVID-19) pneumonia is a recent outbreak in mainland China and has rapidly spread to multiplecountries worldwide. Pulmonary parenchymal opacities are often observed during chest radiography. Currently, few caseshave reported the complications of severe COVID-19 pneumonia. We report a case where serial follow-up chest computedtomography revealed progression of pulmonary lesions into confluent bilateral consolidation with lower lung predominance,thereby confirming COVID-19 pneumonia. Furthermore, complications such as mediastinal emphysema, giant bulla, andpneumothorax were also observed during the course of the disease.
