Accuracy of Magnetic Resonance Imaging in Prenatal Diagnosis of Choledochal Cysts: A Single-Center Retrospective Analysis

Figure 3

Case 8, G23 with CBA. A1–3: fetal MRI. Coronal (4A2–4A3) showed the cyst located in the hepatic hilar, parallel to the hepatoduodenal ligament, higher than the lower edge of the liver, and connected to the hepatic duct (white arrow) and gallbladder (white star)/duct (white triangle). Axial (4A1) showed the intrahepatic bile duct (white arrow) slight dilation. 16D postnatal MRCP (B2–B4) showed that the size of cysts did not change much. The hepatic ducts were slightly dilated (white arrow), the gallbladder (white star) was stiff and caterpillar-like. Coronary T2WI (B2) showed mild edema around the portal vein (white stars). Preoperative cholangiography (B1) confirmed cystic biliary atresia. CBA: cystic biliary atresia. MRCP: magnetic resonance cholangiopancreatography. T2WI: T2 weight imaging.
