A CASE OF STERNUTATION-INDUCED SECONDARY SPONTANEOUS PNEUMOTHORAX IN A PATIENT WITH PNEUMATOCELE FOLLOWING COVID-19 PNEUMONIA

ABSTRACT

SESSION TITLE Pathologies of the Post-COVID-19 World SESSION TYPE Rapid Fire Case Reports PRESENTED ON 10/18/2022 1015 am - 1110 am INTRODUCTION: The development of secondary spontaneous pneumothorax is one of the emerging post-coronavirus-19 disease (COVID-19) complications, more so in mechanically ventilated patients, during the acute phase of infection. High airway pressure delivered during respiratory support is commonly recognized as a potential culprit. CASE PRESENTATION A 57-year-old male was hospitalized for a week for COVID-19 pneumonia with acute hypoxic respiratory failure and treated with oxygen supplementation (required high flow oxygen), remdesivir, and dexamethasone. No mechanical ventilatory support was needed. He had a history of significant smoking cigarettes and marijuana in the past. A week after the discharge, he re-presented to the hospital with complaints of worsening cough, chest pain, and difficulty breathing following three episodes of vigorous sneezing. Computed Tomography (CT) chest revealed large left pneumothorax and right lower lobe pneumatocele. Immediate chest tube insertion relieved his symptoms. The final diagnosis of spontaneous pneumothorax secondary to pneumatocele rupture was made in a patient with a history of COVID-19 pneumonia. DISCUSSION: Cystic lesions resulting from alveolar damage (swelling, inflammation, and fibrosis) with parenchymal damage from the virus, along with barotrauma, are thought to cause pneumothorax. Few cases have been reported in patients without mechanical ventilation. High airway pressures delivered by high flow oxygen, fragile airways due to acute COVID-19 infection, and smoking might have predisposed this patient to pneumatocele, with sneezing leading to rupture and pneumothorax. CONCLUSIONS: This case demonstrates pneumatocele as a sequela of COVID-19, with a risk of pneumothorax. Medical professionals should consider pneumothorax in patients who recovered from COVID-19 and present with new respiratory symptoms. Further studies are required to evaluate the need for routine follow-up imaging (CT chest) in post-COVID-19 infection for pneumatocele or pneumothorax.
