Multiple biliary hamartomas

Case contributed by Thuấn Nguyễn Hoàng


Incidental finding during general ultrasound.

Patient Data

Age: 55 years
Gender: Female

Liver ultrasound demonstrates multiple small foci with comet tail artifacts. With the high frequency transducer, a focus is located adjacent to a portal vein branch, indicating a possible biliary origin. 

Case Discussion

Multiple small foci with comet tail artifact on ultrasound is a typical appearance for multiple biliary hamartomas.  Other differentials to consider include: metastases, multiple abscesses, and calcifications. Other modalities such as MRI, would be helpful for further evaluation.
