Pneumothorax as a late complication of COVID-19.

In late 2019, a novel coronavirus initially related to a cluster of severe pneumonia cases in China was identified. COVID-19 cases have rapidly spread to multiple countries worldwide. We present a typical laboratory confirmed case of COVID-19 pneumonia, that was hospitalized due to hypoxemia but did not require mechanical ventilation. Although initially the patient was evaluated with a favorable outcome, in the third week of the disease, the symptomatology deteriorated due to a massive hypertensive pneumothorax with no known previous risk factor. Since the first cases of COVID-19 have been described, pneumothorax was characterized as a potential, though uncommon, complication. It has been reported that diffuse alveolar injury caused by SARS-CoV-2 can cause alveolar rupture, produce air leakage and interstitial emphysema. Although uncommon, pneumothorax should be listed as a differential diagnosis for COVID-19 patients with sudden respiratory decompensation. As a life-threatening event, it requires prompt recognition and expeditious treatment.
