Conclusion
Extrahepatic biliary cystadenoma is an extremely rare slow-growing tumor
that arises predominantly in female and has malignant potential. It
presents with vague clinical symptoms and clinicians should aware of it
as a differential of gastric outlet obstruction. Moreover they might
face a diagnostic dilemma when radiological investigations cannot
suggest the accurate organ of origin, which can lead to confusion
regarding the treatment to be followed. Hence careful intraoperative
evaluation is required before commencing with the procedure. Complete
surgical resection remains the treatment of choice to prevent both
recurrence and malignant transformation.
