Intrahepatic bile duct stone

Case contributed by Dr Balint Botz

Presentation

Prior cholecystectomy due to gallstones, occasional RUQ discomfort, ERCP planned.

Patient Data

Age: 40 years
Gender: Female
Ultrasound

A non-occlusive stone with a maximum diameter of approximately 4-5 mm, demonstrating posterior acoustic shadowing can be seen centrally in an intrahepatic bile duct of the right lobe. The common bile duct diameter (5-6 mm)  and the intrahepatic bile ducts are within normal limits. 

Ultrasound

The pathology can be better appreciated in the cine loop. 

Case Discussion

A subtle case of hepatolithiasis which required carefuly scrutiny, especially as no other alarming signs such as distal intrahepatic bile duct dilatation were present. The posterior acoustic shadowing is a particularly helpful sign when searching for similar, smaller stones.
