Solitary extra-hepatic hilar peribiliary cyst presenting with obstructive jaundice: a case report

[A case of hepatic peribiliary cysts in a patient with alcoholic liver cirrhosis]

Hepatic peribiliary cysts (HPCs) are characterized by cystic dilatations of the peribiliary glands located throughout the branches of the biliary systems. Specifically, they are mainly located along the hepatic hilum and major portal tracts. The natural history and prognosis of HPCs are uncertain. In fact, almost all HPCs have been discovered incidentally during radiological examination or autopsy, and they are considered to be clinically harmless. Recently, several cases of HPCs associated with obstructive jaundice or liver failure were reported in patients with pre-existing liver disease in several studies. However, until now there have been no reports of such a case in Korea. Herein, we report a case of HPCs that show a disease course with a poor prognosis. These HPCs developed in a 47-year-old man with progressive alcoholic liver cirrhosis.

Therapeutic sclerosis of a small liver cyst that caused obstructive jaundice

The authors describe the case of a small liver cyst (2 cm in diameter) causing obstructive jaundice that was treated with aspiration and therapeutic sclerosis. The procedure was performed with use of a microcatheter and wire system to access the cyst, which was injected with minocycline hydrochloride. At present, 9 months after treatment, the levels of hepatobiliary enzymes are within normal ranges, and no sign of cyst regrowth has been detected on imaging.
