A case of fibrolamellar hepatocellular carcinoma

Fibrolamellar hepatocellular carcinoma is an uncommon histologic subtype of hepatocellular carcinoma, comprising 3.5% of all hepatocellular carcinomas in one large study (Brandt et al 1988). It usually occurs in young people, the average age being 18 years (Farhi et al 1983). It is not associated with cirrhosis and the serum alphafetoprotein is usually normal (Craig et al 1980). Fibrolamellar hepatocellular carcinoma has a more favourable prognosis than the usual hepatocellular carcinoma, with an average survival of 32 months from onset of symptoms, compared to 6 months for the usual type. The resectability rate and 5 year survival figures are also much better (Craig et al 1980). Hence distinguishing this histological subtype is important for surgical management and survival prognosis. This report describes a full radiological evaluation of such a case, covering the wide spectrum of relevant imaging modalities.
