An 81-year-old man with adenocarcinoma of the colon and hepatic lesions later diagnosed as von Meyenburg complex. Axial enhanced CT image of the abdomen, at the level of the porta, demonstrate multiple fluid density lesions (arrows) of varying sizes within the liver. Fluid surrounding the liver is related to underlying large bowel obstruction.

Multiple low-density lesions of varying sizes were identified within the liver, which were non-enhancing in the portal venous phase [Figure 1].
An 81-year-old man with adenocarcinoma of the colon. Hepatic lesions later diagnosed as von Meyenburg complex. B-mode ultrasound image of the liver shows several hyperechoic focal lesions (arrows).

B-mode ultrasound demonstrated multiple hyperechoic lesions [Figure 2] of varying sizes throughout the liver, none of which displayed signal with color Doppler ultrasound.
An 81-year-old man with adenocarcinoma of the colon and hepatic lesions later diagnosed as von Meyenburg complex. Contrast enhanced ultrasound of the liver in the late portal venous phase (1 min 30 sec following injection of contrast) demonstrates non-enhancing lesions (arrow).

No appreciable vascularity was seen within the hepatic lesions in all three phases of the study (arterial, early portal venous, and late portal venous phase) with imaging performed for 3 min [Figure 3].
An 81-year-old man with adenocarcinoma of the colon and hepatic lesions later diagnosed as von Meyenburg complex. Hemotoxylin and eosin stained biopsy specimen shows dilated ducts with inspissated bile (arrow) in an expanded and fibrotic portal tract.

Histology of the focal lesions demonstrated expanded portal tracts with dense stroma, containing dilated bile ducts; a few of which contained inspissated bile [Figure 4].
An 81-year-old man with adenocarcinoma of the colon and hepatic lesions later diagnosed as von Meyenburg complex. In T2-weighted MR sequence of the liver; the focal lesions exhibit high T2 signal (arrows).

TE: 103) signal intensity [Figure 5] and T1 hypointensity with no contrast enhancement [Figure 6]. The multiple liver lesions displayed decreasing signal intensity [Figure 7] with increasing b-values on diffusion-weighted imaging, indicating free diffusion. The imaging findings were in keeping with VMC in addition to simple cysts; metastases being less likely.
An 81-year-old man with colon cancer and lesions in the liver diagnosed as von Meyenburg complex. Post-contrast T1-weighted sequence demonstrate multiple non-enhancing lesions (arrow) throughout the liver.

An 81-year-old man with adenocarcinoma of the colon and hepatic lesions later diagnosed as von Meyenburg complex. Diffusion weighted images of the liver at different b-values reveal negative correlation between the signal intensity of the focal liver lesions (arrow) compared to the b-value, in keeping with free diffusion, which favors benign disease.
