Gastroenterol. [online]. 2024, vol.39, n.1, pp.105-111.  Epub 03-Abr-2024. ISSN 0120-9957.  https://doi.org/10.22516/25007440.1074.

Bile duct cysts are characterized by intrahepatic or extrahepatic bile duct dilation. It is a rare congenital pathology, diagnosed mainly in children. The clinical manifestation in adults is usually nonspecific but essential due to their increased risk of developing carcinoma. We present the case of a 37-year-old female patient who consulted for pain in the epigastrium radiating to the right hypochondrium, associated with emesis and choluria. The hepatobiliary ultrasound was normal, but due to the risk of choledocholithiasis, a magnetic resonance cholangiopancreatography was performed, revealing a cystic dilation of the proximal common bile duct of approximately 2 cm, classified as Todani type I. Bile duct cysts have been associated with several complications, and cholangiocarcinoma is the most important. The probability of malignancy is higher in adults and Todani type I cysts.
