Focal hepatic steatosis: mass-like

Case contributed by Natalie Yang
Diagnosis probable

Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.

CT demonstrates a low attenuation lesion with no distortion of vessels on post contrast imaging, suspicious for fatty infiltration. On non enhanced CT, focal fatty infiltration is suspected if it is 8-10HU less than the spleen.

MRI confirms the abnormality is fat, with T1 in-phase signal intensity higher than the spleen, with uniform signal loss on T1 opposed-phase imaging (not shown). The lesion loses signal on the T2 fat suppressed imaging with vessels seen to course through the lesion without distortion.
