Intrahepatic gallbladder duplication mimicking a hepatic cyst: A case report.

Gallbladder duplication is a rare anomaly of the biliary tree. Implications of misdiagnosis include unwarranted surgery and morbidity such as when liver resections are done suspecting cystic intraductal papillary neoplasm of the bile duct. The use of appropriate imaging, when suspected, facilitates diagnosis and avoids adverse surgical outcomes. We describe a case of an intrahepatic duplicate gallbladder containing calculi detected incidentally during a Focused Assessment Sonography for Trauma after a blunt trauma.
