摘　　要：Knowledge of portal vein(PV)anatomy is important for liver lesion segmentation,surgical methods selection,and intervention procedures.However,PV variants are quite frequent,with an incidence rate of 20-35%(1).Awareness and careful and accurate evaluation before surgery have significant impacts and may help avoid unnecessary complications,especially complex partial hepatectomy and liver transplantation.Herein,we report the case of a 34-year-old woman with a rare PV variant that,to our knowledge,has not been reported before.
