RT Journal Article T1 It seems like cholangiocarcinoma but it is not: discovering the choledochal cyst. A1 Roa Colomo, Amparo A1 Martín-Lagos Maldonado, Alicia A1 Martínez Martínez, Carlos AB A 52-year-old female was referred for a study of a left intrahepatic bile duct dilation with an initial suspicion of Klatskin. Analytically, there was no cholestasis and tumor markers were negative. On echoendoscopy, there was dilation of the intrahepatic bile duct to the confluence at the level of the left hepatic lobe, with no evidence of a lesion that could be biopsied by fine needle aspiration (FNA).
