Lung Point Sign in Ultrasound Diagnostics of Pneumothorax: Imitations and Variants

Figure 7

Double lung point sign. B-mode, linear probe. The left arrow shows the lung point on the left, which is bounded by the Z line, and the right arrow shows the pleural sliding reaching to the rib. Between the left arrow and the rib, a narrow section with the absence of sliding (marked by the asterisk) is visible, indicating a small strip of pneumothorax. A video loop is available as Supplementary File 7.
