RADIOLOGY: HEPATOBILIARY: Case# 33342: FATTY LIVER W/ FOCAL SPARING. The patient is a 54-year-old male with abdominal pain. 1) The hepatic lesion identified on prior CT scan demonstrates signal characteristics described above that are most consistent with an area of focal sparing and diffusely fatty infiltrative liver. The absence of hyperintensity on T2 weighted images and lack of contrast enhancement would not be consistent with hemangioma or metastatic disease. The only other possible etiology for this finding would be a small non-enhancing hepatocellular carcinoma but this is felt unlikely.
