Primary biliary tract neuroendocrine tumors (NETs) are extremely rare tumors that account for 0.2-2% of all gastrointestinal neuroendocrine tumors. The typical presentation is with jaundice and other symptoms related to biliary obstruction.We present a case of right hepatic duct NET in a 27-year-old female patient, asymptomatic, presented for a routine ultrasound examination that revealed moderate dilatation of the intrahepatic biliary ducts and a 20 mm hyperechoic lesion in the right hepatic biliary duct. Additional imaging was performed with the presumptive diagnosis of cholangiocarcinoma. After surgery, the histopathological and immunohistochemical report was conclusive for the diagnosis of G2 well-differentiated NET
