Presentation A 39 Year old female presented with right upper abdominal pain.
Caption: Saggital Sonogram of Liver and Gallbladder.
Description: Saggital view of gallbladder showing multiple, echogenic, non-shadowing, polypoid defects along the anterior gallbladder wall, typical of cholesterol polyps. These show typical ‘ring-down’ artifacts. There is also gallbladder wall thickening, with multiple stones in the fundus, producing posterior shadowing.
Caption: Saggital Sonogram of Gall Bladder
Description: Saggital view of the same gallbladder slightly lateral to the previous image showing polyps along the anterior wall, with multiple stones and sludge in the gallbladder neck.
Caption: Transverse Sonogram of GallBladder
Description: Visible in this Tranverse view again are small polyps attached to the anterior gallbladder wall, producing "Ring Down" artifact.
Caption: Transverse Sonogram of Gallbladder with Color Doppler Imaging
Description: Color Doppler Imaging of the polyps shows "Twinkle Artifact". Twinkling artifact may be seen with color doppler imaging of renal calculi, gallbladder stones, and cholesterol crystals in the gallbladder.
