“…4–7 The best diagnostic clue is the presence of a right upper quadrant cyst communicating with biliary duct and the separate identification of the fetal gallbladder 8. Although MRI9, 10 or three‐dimensional US with multislice view11 may be helpful in prenatal diagnosis, we believe that two‐dimensional US is adequate in most cases, to demonstrate the connection between the gall bladder and the cyst, like in our case.…”

Choledochal cyst is one of the intra-abdominal abnormalities of the biliary ducts that present as a cystic mass in the right upper quadrant abdomen. Prenatal diagnosis has been achieved by the demonstration of a connection between a dilated common bile duct and a cystic lesion. In this report, we describe a pregnant woman in whom routine fetal anomaly scan strongly suggested a choledochal cyst at 29 weeks of gestation by demonstrating a round cystic mass in the right upper quadrant of the abdomen, completely separated from the stomach, bowel loops, and gall bladder, and which showed a connection with the dilated common bile duct.

“…In order to elucidate the exact origin of biliary tract malformations, additional imaging modalities have been proposed: 3D‐US, MRI and fetal MR cholangiography (MRC) . Color Doppler US and MRI are both capable of distinguishing between a dilated intrahepatic vascular system and dilatation of the bile duct .…”

Congenital anomalies of the biliary tract include a variety of pathologic conditions, such as biliary atresia, choledochal cysts, gallbladder agenesis, congenital cholelithiasis, and gallbladder duplication. Although most of these malformations are rare and benign conditions, they may occasionally represent a major threat to extrauterine life. Visualization of a normal‐sized gallbladder should be a mandatory component of the second‐trimester anomaly ultrasound scan. Advances in prenatal sonography enable the detection of biliary tract congenital malformations. In this review, we discuss the detection rates, sonographic features, and prognosis of the most frequently prenatally diagnosed biliary tract malformations.

“…The fetal gallbladder (GB) has become a major target for prenatal ultrasound examination because anomalies of the GB, including nonvisualization, are sometimes accompanied by more severe malformations or diseases, such as biliary atresia, cystic fibrosis, trisomy, and other syndromes (Ochshorn et al,2007; Boughanim etal.,2008; Lee and Kim,2008; Moon et al,2008). Macroscopic assessment of the relationship between the GB and the visceral surface of the liver during fetal periods showed that the GB was not in its usual place or in the fossa, as seen in adults, but that, between 10 and 17 weeks of gestation, it was localized in an intrahepatic position, fully or partly covered by the liver parenchyma (Haffajee,2000).…”

Fetal intrahepatic gallbladder and topographical anatomy of the liver hilar region and hepatocystic triangle

The fetal gallbladder (GB) is embedded in a deep fossa surrounded by the liver parenchyma. Using 15 specimens with intrahepatic GB (crown-rump length 45-92 mm; approximately 9-13 weeks of gestation), we assessed the fetal topographical anatomy of the hepatocystic triangle and the porta hepatis. The cystic duct displayed a long upward course (0.9-4.5 mm along the supero-inferior axis) from the GB, along the duodenum, to the common bile duct in the hepatoduodenal ligament, via an independent mesentery separated from liver parenchyma by a recess of the peritoneal cavity. Notably, the course varied in length among specimens, not among stages. At the porta hepatis, we were able to distinguish the supraportal course of the posterior right hepatic duct overriding a portal vein branch to segment 8 (6/15) from the other, infraportal course (9/15). In the latter type, the portal vein bifurcation was superior to the cystic duct course. Two margins of the hepatocyctic triangle were very long in fetuses because of the inferiorly located intrahepatic GB. Thus, the triangle seems to be difficult to identify in prenatal ultrasound. During changes in location after 9 weeks, the GB fundus remains attached to the liver because the cystic artery was often embedded in the liver parenchyma. A failure in the embedding and re-exposure process of the GB may result in anomalous peritoneal folds around the GB.
