Case 237:   Hepatocellular Carcinoma (HCC)

Diagnostic Category:

Clinical Presentation:

19 year old woman with abdominal discomfort and weight loss.

MR: Large, with necrosis, hemorrhage and pseudocapsule

Imaging Findings:

MR shows typical large moderately differentiated HCC in a non cirrhotic liver. The tumor has numerous patchy confluent areas of hyperintensity on fat suppressed T1 and T2, representing protein rich necrosis or hemorrhage. 

In general, larger HCC occur often in non cirrhotic livers. This mass has larger intralesional arteries, is hypervascular and shows typical washout on equilibrium phase. Note typical pseudocapsule on equilibrium phase, which is not well seen on T2w.
