Classic trifurcation pattern is interpreted when we have a common confluence of the right posterior,right anterior, and left hepatic ducts. In our case it is some sort of complicated trifurcation in which segment 7 posterior right hepatic duct arise directly from the confluence where as the segment 6 posterior right hepatic duct arise as a branch from the right anterior hepatic duct. The gallbladder is not visualized as the patient is status post cholecystectomy. Mild right hydronephrosis is seen as well.
