Multiple Choice

Which statement about major liver tumor types is true?

A benign focal liver lesion that typically appears in young women and has a central scar on imaging is a classic pattern for focal nodular hyperplasia. This lesion arises from a localized hyperplastic response to abnormal arterial blood flow and is not related to cirrhosis. On imaging, it often shows strong arterial enhancement with a central fibrous scar that may light up on delayed phases due to its fibrous tissue. This combination of young female presentation and a central scar is what makes this statement true. Cirrhosis is a major risk factor for hepatocellular carcinoma, but it is not the only tumor type associated with cirrhosis, so the notion that HCC is the only tumor linked to cirrhosis is incorrect. Hepatocellular carcinoma typically shows arterial enhancement with washout and a capsule, not a central scar. Hemangioma is the most common benign liver tumor and grows slowly; it is not malignant and does not enlarge rapidly.
