Multiple biliary hamartomas

Case contributed by Dr Andrew Dixon

Presentation

Asymptomatic.

Patient Data

Age: 35
Gender: Female
Ultrasound

Multiple Biliary Hamartoma. Ultrasound shows many small round echogenic liver lesions and a few larger hypoechoic lesions. 

CT

Multiple Biliary Hamartomas. Portal venous phase CT showing multiple small hypoattenuating liver lesions.

MRI

MR images show multiple small T2 hyperintense and T1 hypointense liver lesions.  Several of the lesions have an enhancing periphery or enhancing nodule.

Case Discussion

Ultrasound, CT and MRI demonstrate numerous liver lesions.

On ultrasound they are generally small and echogenic with a few larger hypoechoic lesions.  CT showed many small 3mm - 25mm hypoattenuating lesions. MR revealed the lesions to be T2 hyperintense and T1 hypointense.  Most lesions did not enhance however some contained an enhancing nodule or peripheral rim of enhancement.

Features were thought to be most consistent with multiple biliary hamartomas (von Meyenburg complexes).
