      Background: Spontaneous pneumothorax is a rarely occurring complication of viral pneumonia in COVID-19. The exact incidence and risk factors are still unclear. In the present work we examine the incidence and outcomes of more than 3,000 patients with pneumothorax who were admitted to our clinic with suspected COVID-19 pneumonia. METHODS: We retrospectively reviewed the cases of COVID-19 patients admitted to our clinic. To calculate the incidence of this event, patients diagnosed with spontaneous pneumothorax were identified and their clinical features were extensively documented. Clinical outcome data were collected. The individual cases are each presented in the form of a short summary. Results: Between March 1st and March 8th June 2020, 3368 patients with suspected COVID-19 pneumonia were admitted to our clinic; of these, 902 patients had a positive nasopharyngeal smear. Six COVID-19 patients who developed spontaneous pneumothorax were identified (0.66%). Baseline imaging showed diffuse bilateral frosted glass opacities and consolidations in these patients, predominantly in the posterior and peripheral lung regions. Four of the six patients were mechanically ventilated. Chest drainage was required in all patients. In all cases there was no direct relationship between the pneumothorax and mortality (66.6%). Conclusion: Spontaneous pneumothorax is a rare complication of viral pneumonia in COVID-19 that can occur without mechanical ventilation.

      Background: Spontaneous pneumothorax is an uncommon complication of COVID-19 viral pneumonia. The exact incidence and risk factors are still unknown. Herein we review the incidence and outcomes of pneumothorax in over 3000 patients admitted to our institution for suspected COVID-19 pneumonia. Methods: We performed a retrospective review of COVID-19 cases admitted to our hospital. Patients who were diagnosed with a spontaneous pneumothorax were identified to calculate the incidence of this event. Their clinical characteristics were thoroughly documented. Data regarding their clinical outcomes were gathered. Each case was presented as a brief synopsis. Results: Three thousand three hundred sixty-eight patients were admitted to our institution between March 1st, 2020 and June 8th, 2020 for suspected COVID 19 pneumonia, 902 patients were nasopharyngeal swab positive. Six cases of COVID-19 patients who developed spontaneous pneumothorax were identified (0.66%). Their baseline imaging showed diffuse bilateral ground-glass opacities and consolidations, mostly in the posterior and peripheral lung regions. 4/6 cases were associated with mechanical ventilation. All patients required placement of a chest tube. In all cases, mortality (66.6%) was not directly related to the pneumothorax. Conclusion: Spontaneous pneumothorax is a rare complication of COVID-19 viral pneumonia and may occur in the absence of mechanical ventilation. Clinicians should be vigilant about the diagnosis and treatment of this complication.
