Choledochal Cyst of Cystic Duct in Children a Rare Entity

Choledochal cyst of the cystic duct is an uncommon entity which may occur as isolated disease or may be associated with choledochal cyst of the other part of the biliary tree. In most of the reported series it was diagnosed at time of operation but now days to better investigation modality it can be diagnosed preoperatively if the index of suspicion is high. We are presenting a series of such case in pediatric age group (which includes an infant) where the diagnosis was made during operation with a light on means and ways for suspecting this entity before operation and how to differentiate other lesion with this entity with relevant review of literature.
