First case report of gall bladder agenesis and absences of extrahepatic biliary system

Abstract

extrahepatic biliary tree anomalies were an extremely rare anatomic anomaly, congenital absence of the gallbladder is commonest. Most of the cases are usually discovered intraoperative, because  pre-operative diagnosis may be a challenges  as patients can present with  symptoms mimicking  biliary colic. ultrasonographic diagnosis in majority of cases may be misleading. We report a first case of  agenesis of the gallbladder and absences of  extrahepatic biliary system.
