Abstract
With the routine use of sonography in the evaluation of suspected gallbladder disease, the familiarity of gallbladder duplication and its differential considerations are essential. Three cases are presented: one surgically proven duplication of the gallbladder, one case in which the sonographic findings were compatible with duplication of the gallbladder, and one surgically proven intraperitoneal fibrous band mimicking a gallbladder duplication. Gallstones were present in all cases and were confined to only one of the two lobes identified in each case. The gallstones did not communicate between individual gallbladder lobes despite multiple patient positions. Contraction of the non-stone-containing lobe was present in one nonfasting patient, which is probably the best indirect sign of a double gallbladder.
