The above images demonstrate the “WES” sign, or “Wall-Echo-Shadow” sign, which is seen when the gallbladder is contracted while full of stones. The sign consists of a clearly defined near wall, echoes from stones within the gallbladder and strong echoes from the stones. The WES sign is diagnostic of cholelithiasis and can be suggestive of cholecystitis, however often the gallbladder wall is within normal limits. In our patient’s case, the gallbladder wall was normal, there was no visible pericholecystic fluid and his CBD was within normal limits. He was evaluated by surgery, given dietary precautions, analgesia and scheduled for outpatient follow up.
