A patient who has had a pleural puncture of the fluidothorax on the right, after which a partial pneumothorax formed.
The ultrasound in in 2D image - displays on both edges of the top of the ribs (R) acoustic shadowing („bat sign“), and a pleural line (PL) with „lung sliding“ when breathing. The point between normal „lung sliding“ and its absence is called the „lung point“ (specific sign of a pneumothorax).
In M-mode we can see the „seashore sign“ – („sand on the shore“), that changes into a „stratosphere sign“ – (horizontal lines above each other) when breathing.
