Fat containing liver lesions represent 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.

Differential diagnosis

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 dermoid
hepatic adrenal rest tumor: can rarely have malignant transformation
post-operative: pack using omental tissue
tamoxifen-induced reversible steatosis
hepatic myelolipoma

Malignant

hepatocellular carcinoma
primary or secondary liposarcoma
