FIG. 6.46 Hourglass Adenomyoma. (A) Sagittal and (B) transverse sonograms show thickening of the gallbladder wall, creating an hourglass
coniguration. At the point of wall thickening, there are innumerable bright echogenic foci with comet-tail artifact, suggesting cholesterol crystals
in Rokitansky-Aschoff sinuses. (C) and (D) Color and spectral Doppler show “twinkling” artifact without real vascularity, supportive of the correct
diagnosis.
FIG. 6.47 Gallbladder Polyps. Small size (≤10 mm) and multiple
tumors are features most suggestive of a benign lesion.
FIG. 6.48 Gallbladder Adenoma. Transverse image through the
gallbladder shows a polypoid lesion found incidentally in a patient with
mild acute cholecystitis. The lesion was a tubulovillous adenoma on
resection.
