title: [Diagnostic ultrasound in pneumothorax].
abstract: For a long time the lung has been regarded as inaccessible to ultrasound. However, recent clinical studies have shown that this organ can be examined by this technique, which appears, in some situations, to be superior to thoracic radiography. The examination does not require special equipment and is possible using a combination of simple qualitative signs: lung sliding, the presence of B lines and the demonstration of the lung point. The lung sliding corresponds to the artefact produced by the movement of the two pleural layers, one against the other. The B lines indicate the presence of an interstitial syndrome. The presence of lung sliding and/or B lines has a negative predictive value of 100% and formally excludes a pneumothorax in the area where the probe has been applied. The presence of the lung point is pathognomonic of pneumothorax but the sensitivity is no more than 60%. Ultrasound is therefore a rapid and simple means of excluding a pneumothorax (lung sliding or B lines) and of confirming a pneumothorax when the lung point is visible. The question that remains is whether ultrasound can totally replace radiography in the management of this disorder.
