Abstract
Two 59-year-old male patients with COVID-19 pneumonia developed pulmonary cavitation with air-fluid level, accompanied by right-sided chest pain several weeks after first onset of symptoms. Considering a possible bacterial abscess formation, both patients were started on antibiotics. No microbiological pathogen was detected in further investigations (sputum analysis, bronchoscopy with bronchoalveolar lavage and CT-guided drainage of the cavitation). Histopathological analysis of the drained fluid was non-specific, and the aetiology remained not fully understood. We report pulmonary cavitation as a rare finding in late stage COVID-19 pneumonia. As both our patients presented with localised chest pain prior to detection of the lesions, new onset of this symptom should warrant further investigation.
