Figure 4

Pseudo-lung point sign. (a) B-mode, linear probe. The vertical arrow indicates the pseudo-lung point. On the left is the preserved pleural sliding, which is terminated by one lung comet. To the right of the arrow is the rigid contour of the pleura above the site of pulmonary contusion. In the pseudo-lung point site, pleural discontinuity is evident, which is not common in the pneumothorax. (b) M-mode, linear probe. Arrows indicate interfaces between a normally aerated and contused lung; however, no barcode sign is present. A video loop is available as Supplementary File 4.
