Hepatocellular carcinoma (HCC) has specific imaging criteria such as arterial hyperenhancement, contrast washout, and pseudocapsule that allow it to be diagnosed with confidence and relative accuracy. However, a novel HCC variant, steatohepatitic hepatocellular carcinoma (SH-HCC), has been described which tends to not exhibit the classic HCC imaging features. In this study, we explored alternative secondary MR features of HCC such as T1 and T2 signal intensity, intralesional fat, and restricted diffusion which may be more applicable in diagnosing steatohepatitic hepatocellular carcinoma.
