Focal fatty sparing of the liver

Case contributed by Dr Bruno Di Muzio

Presentation

Staging for breast carcinoma.

Patient Data

Age: 65 years
Gender: Female

Liver

CT

Diffuse hepatic steatosis with bands and geographic areas of peripheral fatty sparing. The appearances are those of pseudotumors due to the sparing. No discrete metastatic disease. 

18FDG PET-CT

Nuclear medicine

PET-CT with no evidence of metastatic disease. 

Case Discussion

MRI liver has also shown no evidence of metastatic disease (not illustrated on the case). 

Features of diffuse hepatic steatosis with multiple peripheral areas of focal fatty sparing can pose difficulties in assessing for underlying liver lesions such as metastasis.
