Post-COVID-19 pulmonary cavitation and tension pneumothorax in a non-ventilated patient.

Cavitation and pneumothorax are independently associated with high morbidity and mortality in coronavirus disease-2019 (COVID-19). While spontaneous (non-traumatic) pneumothorax formation has commonly been observed among mechanically ventilated COVID-19 patients, there are few rare reports of COVID-19 associated pneumothorax without any history of barotrauma and other conventional risk factors. Here, we report a unique case of post-COVID-19 cavitation and tension pneumothorax which was further complicated by hydropneumothorax formation in a young patient who suffered severe COVID-19 pneumonia 4 weeks back. As the patient was devoid of any conventional risk factors, we believe that persistent inflammatory alveolar damage even after clinical recovery from COVID-19 played a key role in pulmonary cavitation followed by pneumothorax formation. With prompt clinical and radiological recognition of these fatal, yet treatable complications of COVID-19 pneumonia, the patient was saved and had an uneventful recovery.
