Sonographic detection of gallbladder duplication: two cases discovered in utero.
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.
