Representative chest Computed Tomography scans in patients with SARS-CoV-2 pneumonia. a Patient without atelectasis: multiple ground-glass opacities in both lungs (red asterisks), as well as a minimum pleural effusion that do not condition atelectasis. b Patient with small atelectasis. Well-defined, linear opacity is seen in the left lower lobe (red asterisk), corresponding to laminar atelectasis (middle panel). c Patient with large atelectasis. A triangular opacity in both inferior lobes (red asterisk) corresponding to atelectasis is observed, surrounded by pleural effusion in the same location (right panel)
