Spontaneous pneumomediastinum, pneumothorax and subcutaneous emphysema in COVID-19 patients—a case series

BACKGROUND: Spontaneous pneumomediastinum, pneumothorax and spontaneous subcutaneous emphysema are rare entities. A rising trend in the setting of COVID-19 even in patients who are not put on invasive ventilation can suggest an alternative aetiology. CASE PRESENTATION: We describe four cases which presented with suspected symptoms of COVID-19 and were diagnosed with pneumomediastinum, pneumothorax, and subcutaneous emphysema which would have been missed if not for computed tomography scan performed at the time of admission. Three of these cases had no prior history of any iatrogenic intervention, and the fourth person developing pneumothorax and subcutaneous emphysema after intubation. CONCLUSIONS: Pneumomediastinum, pneumothorax and subcutaneous emphysema can be noted as a complication of COVID-19 itself as well as the complication of management of COVID-19.
