A variety of benign and malignant liver lesions may contain macroscopic and/or intracytoplasmic fat in sufficient quantities enabling characterization on imaging studies. Most fat containing liver lesions (80%) in patients with cirrhosis are malignant, most of which are hepatocellular carcinoma ³.

Benign

focal fatty change
hepatic angiomyolipoma
focal nodular hyperplasia
hepatic lipoma
pseudolipoma of the Glisson capsule
xanthomatous lesion of Langerhans cell histiocytosis (LCH)
hepatic adenoma
hepatic teratoma
hepatic adrenal rest tumour: can rarely have malignant transformation
post-operative: pack using omental tissue
tamoxifen-induced reversible steatosis

hepatic myelolipoma

Malignant

hepatocellular carcinoma
primary or secondary liposarcoma
