Multiple hepatic peribiliary cysts discovered incidentally at a medical examination

Abstract

We report a living patient with multiple hepatic peribiliary cysts. It was discovered incidentally during an ultrasonographic screening at a medical examination. Peribiliary cysts are multiple retention cysts of peribiliary glands. Although many autopsy cases of peribiliary cysts have been reported, there are few clinical cases of it in living patients. A CT performed immediately after drip-infusion cholangiography (DIC) was most useful for diagnosis in various imaging tests we performed.
