Lack of Lung Sliding with Pneumothorax
Read Dr. Butts’ article, “Comet Tails and Lung Sliding: Evaluating for Pneumothorax,” in the December 2013 issue, and then view this video that demonstrates lack of lung sliding associated with a pneumothorax. A rib is seen to the right of the image as the structure casting a large shadow. Just beneath the rib, the pleura is seen as a hyperechoic horizontal line. Careful observation reveals that the pleura is not sliding nor are comet tails visible.
