Two cases of hepatic metastatic tumor occurring in irregular fatty liver are reported. These metastatic tumors appeared as irregularly shaped hyperdense areas and were difficult to distinguish from focally spared areas of irregular fatty liver. Even if areas of focal sparing are irregular in shape, hepatic tumors should be carefully ruled out in patients at high risk for liver tumors.
Fatty mass in the intrahepatic portion of the inferior vena cava (IVC) is an unusual lesion. We describe two cases of fatty mass appearing in the lumen of the IVC on CT and MRI study. We assume that this can be regarded as a benign process, and is mostly a normal variant.
We report a 71-year-old male patient with multiple hepatic peribiliary cysts. The six-year follow-up through computed tomography (CT) imaging revealed increases in the size (from less than 10 mm to more than 38 mm) and number of the cysts.
