• Primary tumors are those arising in the liver.
• Secondary tumors are those starting in different organs and spread to the liver.

• Fibrolamellar carcinoma

CT or MRI findings reveal liver with arterial lesions in combination with venous washout

Treatment

• Radiofrequency ablation
• Transarterial chemoembolization
• Transarterial Radioembolization
• Liver transplantation
• Percutaneous acetic acid injection
• Oral sorafenib
