What does shadow on gallbladder mean?
The wall-echo-shadow sign (also known as WES sign) is an ultrasonographic finding within the gallbladder fossa referring to the appearance of a “wall-echo-shadow”: a curvilinear hyperechogenic line representing the gallbladder wall. a thin hypoechoic space representing a small amount of bile.
What is Wall echo shadow?
The wall echo shadow (WES) triad, also known as the double-arc-shadow sign consists of a well-defined near wall, echos from stones immediately beneath the wall, and posterior shadowing caused by strong echoes from stones in the gallbladder fossa.

Acute hepatitis, pancreatitis, pyelonephritis, and peritonitis are inflammatory processes that may secondarily involve the gallbladder and cause wall thickening due either to direct spread of the primary inflammation or, less frequently, an immunologic reaction.
What can we learn from a RUQ ultrasound of the gallbladder?
A RUQ ultrasound was remarkable for echogenic shadowing seen from the level of the gallbladder fossa representing a gallbladder filled with stones (Fig. 1 ). No sonographic Murphy’s sign was elicited. There was no gallbladder wall thickening.
What is the Wes sign in the gallbladder?
The wall-echo-shadow sign (also known as WES sign) is an ultrasonographic finding within the gallbladder fossa referring to the appearance of a “wall-echo-shadow”: a curvilinear hyperechogenic line representing the gallbladder wall a thin hypoechoic space representing a small amount of bile
What does it mean when your gallbladder is looping?
The sign suggests either a large gallstone or multiple small gallstones filling the lumen of a contracted or incompletely visualized gallbladder. Recognizing this finding helps to avoid misinterpretation of a stone-filled gallbladder as a loop of bowel 3.
