Focal fatty infiltration of the liver mimicking a tumor: sonographic and CT features.
Focal fatty infiltration of the liver detected by ultrasonography (US) in this asymptomatic woman had unusual features. It appeared as a sharply marginated, spherical mass lesion on CT, with soft tissue attenuation values of 30 HU unenhanced and 50 HU with enhancement. This tumor-like zone completely resolved on follow-up US and CT, underscoring the need for follow-up examinations to exclude primary or metastatic tumors. Our review of the literature failed to reveal previous reports of features such as these.
