Benign focal liver lesions: The role of magnetic resonance imaging

Figure 10  A 57-year-old male underwent abdominal computed tomography scan with contrast for the evaluation of a renal mass demonstrating a hepatic lesion in S3, hypodense on contrast-enhanced computed tomography. Liver magnetic resonance imaging (MRI) confirmed the presence of a nodule hypointense on T1-weighted sequences, slightly hyperintense on long TR sequences, without significant restriction on the ADC map. During dynamic study after intravenous contrast injection (gadoxetic acid), the lesion does not have significant enhancement and it appears hypointense on the hepatobiliary phase. At 11 mo follow-up, the nodule shows stable dimensions and MRI signal features. These features are consistent with fibrous hemangioma.
