Objective:
To report the in utero diagnosis of a duplicated gallbladder.
Methods:
Obstetric sonography was performed at 2 separate referral centers. A comprehensive level 11 examination was performed at each center.
Results:
In both cases, a duplicated gallbladder was detected in utero without the presence of other anatomic abnormalities.
Conclusions:
Gallbladder duplication, although uncommon, should be considered when an additional cystic structure is seen in the right upper quadrant. Recognition of the presence of a duplicated gallbladder, a relatively benign condition, prevents invoking a more serious diagnosis, such as a choledochal or duodenal duplication cyst.
