We present the case of a 40-year-old female who presented to the General Surgery clinic due to a single episode of abdominal pain which required a visit to the Emergency Department. The patient had undergone surgery during childhood due to the suspicion of a hepatic hydatid cyst. However, an intraoperative cholangiography identified a small, non-complicated biliary cyst. Therefore, a hepatic resection was not performed. The patient did not undergo follow-up of the lesion. A large intrahepatic biliary cyst of 50 x 40 x 35 mm (type V, Todani classification) 1 was identified via ultrasound; it originated from the right hepatic bile duct, with lithiasis inside. This finding was corroborated via nuclear magnetic resonance (NMR) (Fig. 1 and Fig. 2). Type V biliary cysts are infrequent and they usually consist of multiple intrahepatic cysts 1. Our patient presented with a large single intrahepatic cyst, which highlights the singularity of this case. In addition, cystolithiasis is a rare finding in biliary cysts, especially in type V 2. Both the hepatic analytical profile and tumor markers were normal. The patient had not suffered previous cholangitis episodes. Despite the fact that type V biliary cysts have a low risk of malignancy, the optimal management of these lesions is surgical resection. Nevertheless, a strict radiologic surveillance was decided upon due to the numerous family related issues that the patient was going through 3.
