title: Atypical magnetic resonance imaging findings in hepatocellular carcinoma.
abstract: Magnetic resonance imaging (MRI) is currently the modality of choice to evaluate liver lesions in patients with cirrhosis and hepatitis B and C. Hepatocellular carcinoma demonstrates typical imaging findings on contrast-enhanced MRI, which are usually diagnostic. Unfortunately, a subgroup of hepatocellular carcinoma presents with atypical imaging features, and awareness of these atypical presentations is important in ensuring early diagnosis and optimal patient outcomes. Herein, we review some of the more common atypical presentations with a focus on MRI.
