A case of gallbladder cancer with accompanying right hepatic artery, common bile duct, and pancreatic invasion for isolated lymphnode metastasis

Abstract

A patient was a 66-year-old female. Abdominal multi-detector row CT (MD-CT) showed 31×25 mm of a low-density mass in the pancreatic head, and 10×10 mm of slightly enhanced tumor in the gallbladder was indicated by computed tomography multi planar reconstruction (CT-MPR). Abdominal angiography revealed the tumor invaded the trunk of the right hepatic artery. She underwent the pancreatoduodenectomy with the right hepatic artery resection dispensed with reconstruction. Since lymph node tissue was seen in the pancreatic head mass by pathological examination, we diagnosed that isolated lymph node metastasis from the gallbladder cancer directly invaded to the pancreas and bile duct. This case was a rare advanced gallbladder cancer, in which isolated lymph node metastasis showed direct invasion of the pancreas and bile duct, presenting a pancreatic tumor-like appearance.
