Abstract
A 69-year-old female with fever, a pancreatic mass and portal vein thrombosis was referred to our hospital. Blood culture test was positive for Escherichia coli. Abdominal contrast-enhanced CT revealed a heterogeneously enhanced oval mass in the head of the pancreas with a size of 16×14mm, and a non-enhanced nodule in the portal vein, which was adjacent to a cystic lesion in the body of the pancreas. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of the mass in the head of the pancreas indicated adenocarcinoma. On the diagnosis of pancreatic cancer with infectious pseudocyst and portal vein thrombosis, she underwent subtotal stomach-preserving pancreaticoduodenectomy and partial round resection of the portal vein. Histopathological findings of the resected specimen revealed pancreatic head cancer followed by pancreatitis which caused the pancreatic pseudocyst. Infection of the pancreatic pseudocyst would lead to the communication between the cyst and the portal vein. This is the first case with pancreatic cancer with infectious pancreatic pseudocyst communicating to the portal vein.
