Findings:

2 tubular side by side hypoechoic structures in the mid abdomen extending from the biliary system in the region of the gallbladder. No vascular flow demonstrated on doppler ultrasound.

Diagnosis: Duplicated Gallbladder in a fetus.
Discussion:

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. However there has is an increased prevalence of cholelithiasis and intermittent cystic duct obstruction that has been reported with duplication.


Nonvisualization of the gallbladder has been associated with fetal malformations. Increased prevalence of cholelithiasis and intermittent cystic duct obstruction that has been reported with duplication.

Duplication of the gallbladder has been described by the Boyden Classification.

Classification of Boyden for gallbladder duplication.

A, Septate gallbladder.
B, Fundic duplication.
C, Body duplication.
D, Y-shaped gallbladder.
E, Complete duplication.
F, Bilatera
l gallbladders.
