Patient
female, 49 year(s)
 
 
  • Figure 1
    CT study
     

    No clear abnormality can be detected at the unenhanced scan

     
    Area of Interest: unknown; Imaging Technique: CT study;

    Contrast-enhanced CT: arterial phase. A large enhancing lesion of the right hepatic lobe is visible.

     
    Area of Interest: unknown; Imaging Technique: CT study;

    Contrast-enhanced CT: portal phase. The lesion becomes isodense to the normal liver parenchyma.

     
    Area of Interest: unknown; Imaging Technique: CT study;
     
     
  • Figure 2
    Unenhanced MR

    Unenhanced SE T1 weighted MR image (0.5 T). No clear abnormality can be detected. The presence of a nodule can only be suspected on the basis of the displacement of the portal vein

     
    Area of Interest: unknown; Imaging Technique: Unenhanced MR;
     
     
  • Figure 3
    Dynamic MR examination
     

    Dynamic MR sequence (0.5 T): unenhanced T1 weighted image. The presence of a nodule can be suspected at the level of the 1st hepatic segment.

     
    Area of Interest: unknown; Imaging Technique: Dynamic MR examination;

    Dynamic MR sequence (0.5 T): enhanced T1 weighted image: early arterial phase. The nodule shows marked enhancement with respect to the normal liver parenchyma.

     
    Area of Interest: unknown; Imaging Technique: Dynamic MR examination;

    Dynamic MR sequence (0.5 T): enhanced T1 weighted image: arterial phase. The central portion of the nodule is hyperintense to the peripheral zone.

     
    Area of Interest: unknown; Imaging Technique: Dynamic MR examination;

    Dynamic MR sequence (0.5 T): enhanced T1 weighted image: portal phase. The central portion of the nodule is still slightly hyperintense with respect to the peripheral zone.

     
    Area of Interest: unknown; Imaging Technique: Dynamic MR examination;

    Delayed SE T1 weighted image after contrast administration (0.5 T): the lesion is again isointense to the normal liver parenchyma
