AB Key  PointsCholedochal  cyst  refers  to  dilation  of  the  common  bile  duct,  with  type  I  being  the  most  common  and  the  only  prenatally  diagnosed  form.Prenatal  diagnosis  is  based  on  the  visualization  of  a  single  simple  cystic  structure  near  the  gallbladder.Differential  diagnosis  includes  hepatic,  adrenal  or  renal  cysts,  duodenal  duplication,  and  gallbladder  duplication.There  is  no  need  to  alter  the  management  of  pregnancy,  nor  the  timing  or  mode  of  delivery,  following  the  prenatal  diagnosis  of  choledochal  cyst.During  the  newborn  period,  detailed  imaging  of  the  biliary  system  is  required  to  exclude  biliary  atresia,  including  radionuclide  imaging.Definitive  treatment  requires  surgical  excision  of  the  cyst,  and  long-term  outcome  is  excellent.
