This sonogram of the right upper quadrant is demonstrating which sign?

The correct choice, the WES sign, refers to a specific ultrasound finding often associated with the presence of gallstones and gallbladder pathology. In a sonogram of the right upper quadrant, the WES sign indicates the presence of a gallbladder filled with stones. This sign typically presents as a combination of three components: the gallbladder wall, the echogenic interface of the stones, and the echogenicity of the liver surrounding the gallbladder.

The WES sign is significant in clinical practice because it aids sonographers and physicians in diagnosing gallstones and evaluating gallbladder conditions. By recognizing this pattern on an ultrasound, practitioners can make informed decisions about further imaging, management, or surgical interventions for gallbladder disease.

The other signs mentioned, such as the Olive sign, Target sign, and Doughnut sign, are representative of different clinical scenarios or anatomical presentations, which would not relate directly to gallbladder pathology in the right upper quadrant imaging context typically associated with the WES sign.
