Spontaneous massive hemothorax as a complication of necrotizing pneumonia in a patient with severe acute respiratory syndrome coronavirus 2 induced acute respiratory distress syndrome: a case report

We present an unusual bleeding complication in a patient with severe acute respiratory distress syndrome in coronavirus disease 2019.

The patient, a 63-year-old Caucasian man, received venovenous extracorporeal membrane oxygenation support after rapid deterioration of lung function on day 6 after admission to hospital. After initial stabilization on lung protective ventilation and prone positioning, he started to develop mild bleeding complications until he went into occult profound hemorrhagic shock. Causative was a massive hemothorax of the right hemithorax with mediastinal shifting due to spontaneous bleeding from a pulmonal artery in a heavily remodeled right inferior lobe. Histopathological examination of the resected tissue showed signs of an organizing fibrinous pneumonia with focal parenchyma necrosis. After surviving a massive bleeding event caused by necrotizing pneumonia, the patient made a swift recovery and was discharged to rehabilitation 31 days after initial hospital admission.

The combination of severely elevated inflammatory markers and pulmonary hemorrhage should arouse suspicion of necrotizing pneumonia. In necrotizing pneumonia, the possibility of severe intrathoracic bleeding complications should be kept in mind if it comes to sudden deterioration of the patient.
