An unusual cause of pain in the right hypochondrium.

Choledochal cyst is an uncommon anomaly of the biliary system. It manifests by cystic dilation of the extra or intrahepatic biliary tract or both. Three cases of choledochal cysts are reported, who had presented with pain in right hypochondrium. All the three patients presented in one Surgical Unit of a Teaching Hospital within a span of three months. The first patient was initially managed as obstructive jaundice, second as acute pancreatitis and third patient as a case of pancreatic pseudocyst. However, after investigations, the final diagnosis in all three of them was the same i.e. choledochal cyst which was managed by Roux-en-Y hepatico-jejunostomy.
