Lethal case of lung gangrene against the background of viral-bacterial pneumonia (COVID-19 and Fusobacteria)

Abstract

The respiratory system is the main target of infection (COVID19) spread by the SARS-CoV-2 virus. The article presents a case of the development of viral-bacterial pneumonia caused by SARS-CoV-2 and Fusobacteria, complicated by the development of gangrene of the lower lobe of the right lung with abscess formation. Clinical case. The patient was admitted for inpatient treatment, accompanied by an ambulance team for emergency reasons, with complaints of pain when coughing, shortness of breath, cough with mucopurulent sputum, fever up to 39.60C. On computed tomography of the chest: signs of viral-bacterial pneumonia. Infiltration was determined in the region of the lower lobe of the right lung, against which a cavity with melting lung tissue was revealed. The result of a virological study of a swab from the throat and nose: SARS-CoV-2 coronavirus RNA was detected. Despite treatment, the patient died. Autopsy revealed signs of viral-bacterial pneumonia and a decaying cavity with purulent contents, diffuse destructive changes with hemorrhages. Conclusion. The cause of death of the patient was a new coronavirus infection COVID-19, which caused bilateral viral-bacterial pneumonia, complicated by the development of gangrene of the lower lobe of the right lung with abscess formation.
