It seems cholangiocarcinoma but it is not: discovering the choledochal cyst.

IT SEEMS CHOLANGIOCARCINOMA BUT IT IS NOT: DISCOVERING THE CHOLEDOCHAL CYST. Rev Esp Enferm Dig. 2020 Nov 25;: Authors: Roa-Colomo A, Martín-Lagos Maldonado A, Martínez-Martínez C Abstract 52-year-old woman referred for suspected Klatskin tumor. In echoendoscopy at the level of the left hepatic lobe, there is dilation of the intrahepatic bile duct until the confluence without evidence of injury at this level susceptible of FNA. ERCP is performed and in the left hepatic duct, close to the hilum, a 1-cm stenosis and a large suprastenotic dilation are observed. Abdominal MRI is repeated 3 months later with slight dilation of the right intrahepatic bile duct and dilation of the left hepatic bile duct with a suggestive image of stenosis. Dilated extrahepatic bile duct (12 mm) that gradually tapers to the papilla. Choledochal cyst type IVa of Todani. In an expert committee, a resection of the cyst and a hepatic jejunostomy in Roux-en-Y were decided. Choledochal cysts are a rare congenital anomaly, consisting in single or multiple dilation of the intra and / or extrahepatic bile ducts. The risk of cholangiocarcinoma is 2.5-25% in adults and 0.7% in children. The best diagnostic methods are echoendoscopy and MRI and they are classified according to Todani classification. The treatment consists in cyst resection and Roux-en-Y hepaticoduodenostomy or hepaticojejunostomy. The risk of malignancy is present after resection, so periodic monitor...
