Abstract

The development of spontaneous pneumomediastinum and subcutaneous emphysema are few of the rare clinical manifestations observed in coronavirus disease-19 (COVID-19) patients which are yet to be fully understood. Most cases of spontaneous pneumomediastinum arise due to factors causing high intra-alveolar pressure. Herein, we report a case of a COVID-19 positive elderly male, who presented with spontaneous pneumomediastinum and subcutaneous emphysema unrelated to high-pressure ventilatory measures, detected on chest computed tomography (CT). Despite acute medical care, the patient progressed towards a more serious clinical course. Male gender and diffuse alveolar damage caused by COVID-19 seems to be the most relevant association in this case. However, we have enlightened other possible pathological mechanisms and their association with severity index of COVID-19.
