LUS showed an evolution with diffuse B lines [Fig. 1a] and large consolidations at the lower lobes [Fig. 1b, Fig. 1cb-c]. LUS score of 31. LUS showed wide appearance of air-bronchogram [Fig. 1d - Fig. 1e]. LUS score of 16.

Large hypoechoic and irregularly bordered consolidation in the left lower lobe (day 9).

fig1b
LUS revealed diffuse interstitial involvement [Fig. 2a], with a large consolidation at the right lower lobe [Fig. 2b]. Pleural effusion with lobar atelectasis was found at the left lower lobe [Fig. 2c]. LUS examination showed B lines reduction and broader signs of air-bronchogram within the consolidations [Fig. 2d]. LUS score 16 with pleural effusion.

Large consolidation with partial irregular air-bronchogram (hyperechoic punctiform or linear images) on the left edge, in the right lower lobe (day 9).

LUS highlighted the persistence of large consolidations at the lower lobes (right consolidation measured 90 x 33mm, the left 42 x 30 mm) [Fig. 3a Fig. 3b]. LUS score of 26. Eight days after (day 25), the patient progressively became eupneic, consolidations showed reduction in size (right consolidation 66 x 21mm, left 24 x 30 mm) and increase in air-bronchogram (Fig. 3c - Fig. 3d).
PMC7691824_04
Large consolidation with complete air-bronchogram on the left edge and a clear border, in the right lower lobe (day 16).

fig1d
LUS, diffuse B lines with white lung at the bases [Fig. 4a] and small consolidations at the apices were visible [Fig. 4b]. LUS score of 25. Seven days after (day 15), diffuse B lines and patchy white lung pattern persisted, without appearance of consolidations (LUS score of 21) [Fig. 4c - Fig. 4d] and stable
