RE: Communication between the Cystic Lesions of the Liver and Biliary Tree: How Can We Evaluate Efficiently and Safely?

We have read the recent interesting article titled “Monosegmental Hepatobiliary Fibropolycystic Disease Mimicking a Mass: Report of Three Cases” by Kwon et al. (1), published in Korean Journal of Radiology. In this article, the authors briefly discussed the management of the biliary cystic lesions of the liver particularly fibropolycystic liver disease such as Caroli’s Disease. As mentioned by the authors in the article, these cystic lesions are formed by remodeling the ductal plate and communicating with the biliary tree. The authors stated that different types of fibropolycystic liver disease demonstrate characteristic findings at computed tomography (CT) and magnetic resonance (MR) imaging. Ultrasonography (US), CT, magnetic resonance cholangiopancreatography (MRCP), percutaneous transhepatic cholangiography, and endoscopic retrograde cholangiopancreatography can show the dilated
