title: Solitary hepatic lesions with a hypoechoic rim: value of color Doppler sonography.
abstract: OBJECTIVE
  A hypoechoic rim around a focal liver lesion as revealed by conventional sonography may be present in malignant liver lesions as well as in benign liver lesions. This study evaluated the potential of color Doppler sonography in differentiating various focal liver lesions with a hypoechoic rim.
  
  
  CONCLUSIONS
  Color Doppler sonography may be helpful in distinguishing focal nodular hyperplasia (FNH) from other focal liver lesions. The characteristic finding of blood flow within the hypoechoic rim of FNH is most likely caused by small vessel abnormalities that have previously been described for FNH.
