A 49-year-old Caucasian man was admitted to the Emergency Department for shortness of breath and cough. CT imaging showed bilateral a mild COVID-19 related pneumonia. He was hospitalized in the low-intensity COVID-19 unit where he received O2 therapy and oral corticosteroids (CS). Three weeks after discharge a high-resolution computed tomography (HRCT) find a giant bulla of the inferior lobe. The bulla was resected by video-assisted thoracoscopic surgery (VATS) and the patient recovered completely. In our patient, it is reasonable to suspect that the development of the bulla is a result of SARS-CoV-2 infection, since no bulla was observed in the first HRCT two months before. SARS-CoV-2 related pneumonia may be responsible for lung remodeling due to diffuse alveolar damage and later interstitial myofibroblastic proliferation. Corticosteroids might have played a role in increasing SARS-CoV-2 dystrophic action. COVID-19 leads to pulmonary damages, which are still partially unknown and might result in development of bullae. In fit patient surgical treatment can be carried out safely.
