From the case:
Intrahepatic bile duct stone

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.
From the case:
Intrahepatic bile duct stone
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/72141/annotated_viewer_json?lang=us"}
The pathology can be better appreciated in the cine loop.
Case Discussion
A subtle case of hepatolithiasis which required careful 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.
