Patient Data
Age: 36
Gender: Male
From the case:
Multiple biliary hamartomas

Axial C+ portal venous phase
Gallstones within the body and fundus of the gallbladder with the adjacent gallbladder contracted around the gallstones. The described cystic lesion within the porta hepatis represents the residual non-contracted proximal gallbladder. Multifocal small 3-4 mm hypodensities throughout the liver parenchyma with progressively enhancing liver parenchyma within segment 7 which may relate to Von-Meyenburg complex (biliary hamartosis).
From the case:
Multiple biliary hamartomas
The liver contains innumerable small echogenic "nodules"measuring up to 3 mm
in both lobes. There are also several small cysts.
There is no convincing liver surface or hepatic vein wall nodularity. Portal
vein Doppler is unremarkable with no evidence of portal hypertension.
Large gallbladder calculi noted.

Axial T2
Innumerable tiny T2 hyperintense lesions throughout the liver parenchyma
measuring between 2-10 mm consistent with biliary hamartomas. The lesions
are most marked within a subcapsular distribution throughout the right lobe.
No intrahepatic or extrahepatic biliary duct dilatation. Similar to the
previous CT study there is gallstone is present within the fundus of the
gallbladder. Spleen, adrenals, kidneys, pancreas, pancreatic duct and
visualized bowel are within normal limits.
Impression:
Multiple biliary hamartomas consistent with Von Meyenburg complex.
