Secondary Spontaneous Pneumothorax in a COVID-19 Recovered Patient.

Coronavirus disease 2019 (COVID-19) is an infectious disease primarily affecting the lungs with a spectrum of post-viral complications. There are well-described examples of pneumonia, empyema, pneumomediastinum, and spontaneous pneumothorax cases following COVID-19 infection within the literature. However, there is insufficient evidence implicating the cause of spontaneous pneumothorax in COVID-19 recovered patients. We present a previously infected COVID-19 patient who developed a secondary spontaneous pneumothorax two weeks after recovering. A review of the literature for similar cases was limited and therefore includes a summary of recommendations. Overall, the literature establishes that pneumothorax can occur during different phases of COVID-19 in patients without a history of pulmonary disease or barotrauma and is not necessarily associated with the severity of the viral infection. As in the case of our patient, the culmination of chronic inflammatory changes and an acute exacerbation from COVID-19 further predisposed him to a secondary spontaneous pneumothorax. In summary, all cases of recovered COVID-19 patients should maintain close follow-up with their physician and seek medical attention if acute respiratory symptoms develop.
