Normvarianten des Gallenwegssystems

Type Va

extrahepatic bile duct duplication: a case report. Modified double common bile duct classification proposed by Choi et al. [4] (Our case arrowed)

Type Va

extrahepatic bile duct duplication: a case report. Magnetic resonance cholangiopancreatography. Right red arrow – gall bladder draining to right hepatic duct. Right yellow arrow – right hepatic duct. Left yellow arrow – left hepatic duct. Left red arrow – abrupt cutoff point and choledocholithiasis in common bile duct

Anatomical

variations of cystic duct insertion and their relationship with choledocholithiasis: an MRCP study. Schematic demonstration of cystic duct confluence with extrahepatic bile duct. The craniocaudal insertion level is labeled by the letters H, M and L indicating high, mid and low insertions, respectively (a). The transverse site of insertion is labeled by the letters L, A, M and P indicating lateral, anterior, medial and posterior insertions, respectively (b)

Anatomical

variations of cystic duct insertion and their relationship with choledocholithiasis: an MRCP study. The 3D volume rendering MRCP images demonstrate the high-lateral (a), mid-anterior (b), mid-posterior (c), mid-medial (d), mid-lateral (e), and low-medial (f) insertions of the cystic duct

Anatomical

variations of cystic duct insertion and their relationship with choledocholithiasis: an MRCP study. A patient with mid-lateral insertion of cystic duct and choledocholithiasis. The coronal a MRCP image depicts the mid insertion level, and the axial b MRCP image shows the lateral insertion site. Note the insertion point (arrows) and the multiple stones (arrowheads) in the common bile duct

Anatomical

variations of cystic duct insertion and their relationship with choledocholithiasis: an MRCP study. A patient with low-medial insertion of cystic duct with no choledocholithiasis. The Coronal (a) and 3D volume rendering (b) MRCP images demonstrate the low medial insertion (white arrow) of cystic duct with no stone in the common bile duct

Antenatally

detected cystic biliary atresia: differential diagnoses of a double bubble. Antenatal ultrasound at 36 weeks gestation. Two fluid filled structures in the fetal abdomen: a ‘double bubble’ sign.

Antenatally

detected cystic biliary atresia: differential diagnoses of a double bubble. Abdominal ultrasound of the right upper quadrant. A large anechoic cystic lesion is seen outside the liver, in the region of the porta hepatis, measuring 38 mm. Another smaller extrahepatic cyst is seen. There is no intrahepatic duct dilatation.

Antenatally

detected cystic biliary atresia: differential diagnoses of a double bubble. Coronal plane (a) and Transverse plane (b) T2-W Trufi Magnetic Resonance Cholangiopancreatography at 8 days old. Two cystic lesions are demonstrated in the extrahepatic biliary tree, largest measuring 32.8 mm x 40 mm. There is no intrahepatic biliary dilatation and a lack of continuity of the extrahepatic biliary tree with the duodenum, suggesting a diagnosis of CBA rather than a choledochal cyst.

Antenatally

detected cystic biliary atresia: differential diagnoses of a double bubble. Cholangiogram showing large cystic dilatation and abnormal etiolated, hypoplastic intrahepatic biliary ducts consistent with cystic biliary atresia.

Antenatally

detected cystic biliary atresia: differential diagnoses of a double bubble. Post natal abdominal US scan. Shows the cystic lesion and a gallbladder that is seen to be convoluted and abnormal in position and morphology.
