case_images: Intraoperative endoscopic retrograde cholangiogram demonstrates a long common channel (green arrow) joining the pancreatic duct (white arrow) with the common bile duct. Note the fusiform dilation of the common bile duct (red arrow) into which the gallbladder (blue arrow) and cystic duct drain consistent with Type 1A choledochal cyst.

case_images: Otherwise, PET/CT revealed no evidence of distant metastases (Figs. 1, 2, 3, Fig. 4, Fig. 5).
case_images: Abdominal MRI/ MRCP coronal Maximum Intensity Projection reconstructed image shows a long common channel (green arrow) suggestive of PBM. Significant dilation of the common bile duct (red arrow) is noted into which the gallbladder and prominent cystic duct drain (blue arrow) consistent with Type 1A choledochal cyst.

case_images: Otherwise, PET/CT revealed no evidence of distant metastases (Figs. 1, 2, 3, Fig. 4, Fig. 5).
case_images: T2 weighted MRI/ MRCP coronal image of the upper abdomen without intravenous contrast shows marked abnormal dilation of the extrahepatic biliary tree suggestive of choledochal cyst. The arrow indicates focal, mass-like thickening of the distal common hepatic duct with associated stricture highly concerning for malignancy. Upstream dilation of the common hepatic duct and intrahepatic biliary tree is noted.

case_images: Classification of PBM proposed by the JSPBM. Type A = stenotic type, in which a distal common bile duct with stenosis joins the common channel. Type B = nonstenotic type, in which a distal common bile duct without stenosis joins the common channel. Type C = dilated channel type, in which the common channel is dilated. Type D = complex type, in which the PBJ has formed in a complicated configuration.
