Excerpt

Ultrasound has been widely used in the critical care setting for timely and accurate diagnosis of life-threatening conditions. Pneumothorax is one such condition and typically is confirmed by the presence of the following ultrasonographic findings: abolished lung sliding or lung pulsing, a stratosphere sign, the absence of B lines, and the presence of lung point [1,2]. In particular, lung point is demonstrated to have 100% specificity for the diagnosis of pneumothorax [3]. Here, we present a sign that mimicked the findings of lung point but that was identified in healthy lung. To the best of our knowledge [4,5], this has never been described. …
