Laparoscopic management of gallstones in a duplicate gallbladder with double cystic ducts: A case report

Figure 1 Abdominal ultrasound showing abnormal echoes in the region of the gallbladder, indicating a double gallbladder malformation. A and B: The B-ultrasound images at different angles and sections. The sizes of the two gallbladders are 52 mm × 26 mm and 43 mm × 21 mm respectively. The orange arrows indicate the gallbladder cavity. Multiple strong echoes with posterior acoustic shadowing are observed in one gallbladder cavity, providing evidence to indicate the presence of multiple stones.

Figure 2 Computed tomography scan showing a duplicated gallbladder. No gallstones are discernable on the tomographic images. A and B: The different layers of the computed tomography scan. The orange arrows indicate the gallbladder cavity.

Figure 3 Magnetic resonance cholangiopancreatography showing a double gallbladder anomaly, with a nodular low signal in one of the cavities, which is assumed to indicate the presence of stones. Neither the common bile duct nor the hepatic ducts are dilated. A: T2-weighted imaging coronal view; B: T2 fat-suppressed axial view. The orange arrows indicate the gallbladder cavity.
