Abstract: | Non-hypervascular hypointense nodules (NHHNs) on gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid–enhanced magnetic resonance imaging (EOB-MRI) have a high likelihood of hypervascularization progressing to typical hypervascular hepatocellular carcinoma (HCC). NHHNs that were present before the start of anti-hepatitis C virus (HCV) therapy is a risk marker for HCC development after achieving sustained virologic response (SVR). In this report, we show a patient without a previous history of HCC in whom HCC developed by hypervascularization of NHHN after SVR. This patient achieved SVR more than 8 years before NHHN developed into HCC, and during this time NHHN had been present but had remained unchanged in size and imaging features as shown by repeated EOB-MRI. Hepatocarcinogenic potential of NHHNs persist for a long time after SVR, despite the eradication of HCV. |
