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 3-25 mm 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).
