Computed tomographic and ultrasound appearances of focal spared areas in fatty infiltration of the liver.
Computed tomography (CT) and ultrasound (US) appearances of diffuse and focal fatty infiltration of the liver (FIL) are well recognized. We have recently seen 10 cases with "fat spared" areas in FIL presenting as pseudo tumours of the liver. Characteristic appearances of fat free areas in FIL which help differentiate these areas from other focal liver lesions include (i) location in the medial segment of the left lobe of the liver, (ii) absence of mass effect on surrounding vessels and liver tissue, and (iii) presence of typical changes of FIL elsewhere in the liver on CT or US examination.
