Choledochal Cyst in an Identical Twin

A 15-year-old girl underwent an excisional procedure for
the treatment of a choledochal cyst with an anomalous pancreatobiliary junction.
Her sister, an identical twin, was perfectly healthy without any abnormality
in the hepatobiliary system as demonstrated by ultrasound, ERCP, and infusion
cholangiography. Choledochal cysts and pancreatobiliary malunions are possibly
caused by developmental accidents in early intrauterine life rather than
by genetic factors, because of the rarity of familial development and lack
of occurrence in both members of a pair of identical twins.
