female, 37 year(s)
 
 
  • Figure 1
    Liver ultrasound

    Polylobulated hypoechoic lesion (approximately 3.5 maximum diameter) in the right liver lobe, with some thin echoic septa.

     
    Area of Interest: Liver; Imaging Technique: Ultrasound;

    Unenhanced MRI
     

    Before intravenous contrast, the liver lesion appears hypointense on T1-weighted (a), conventional (b) and fat-suppressed T2-weighted (c) images, with lobulated contour, without restricted diffusion (d, b=600).

    During dynamic gadolinium-enhanced acquisition (a-c) the lesion appears avascular save for thin, minimal septal enhancement increasing from the venous to the delayed phases.
