COVID-19 Bullous Lung Disease Superinfection by Raoultella planticola.

Bullous lung lesions from coronavirus disease 2019 (COVID-19) pneumonia, causing pneumothorax, are a rare complication, affecting up to 1% of infected patients. Raoultella planticola is an aerobic, gram-negative bacteria known to cause opportunistic infection. We present a rare case of spontaneous pneumothorax from rupture of lung bulla as a late sequela from COVID-19 pneumonia and superinfection of the bulla by R. planticola. Although superinfection of bullous lesions is known, this is the first reported case of R. planticola pneumonia in a patient with COVID-19 lung bullae. COVID-19 patients are at heightened risk for bullous lung lesions and superinfection by opportunistic organisms; thus, they should be followed up closely.
