Cystohepatic (Calot) triangle (diagram)

Case contributed by Assoc Prof Craig Hacking

The cystohepatic (Calot) triangle is a triangle in the porta hepatic with the boundaries:

  • right: the cystic duct which is often tortuous and has a beaded appearance, passes downward and to the left to join the common duct
  • left: common hepatic duct 
  • superior: the inferior surface of the liver (in the original description by Calot the superior boundary is the cystic artery)
