Abstract

In December 2019, coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was reported in Wuhan, China. An 82-year-old woman presented to our hospital with high fever (39°C) and chest computed tomography revealed ground-glass opacities in the left lung apex. She was positive for SARS-CoV-2 based on a polymerase chain reaction test, and diagnosed with COVID-19 pneumonia. 6 months after treatment, chest CT showed a large bulla (47 mm × 29 mm) in the left lung apex, although pneumonia had partially resolved. Radiologic follow-up is needed after COVID-19 pneumonia, because patients may develop bullae after treatment.

Keywords: Bulla; COVID-19; Coronavirus; Pneumonia; SARS-CoV-2.
