Patient
female, 21 year(s)
 
 
  • Figure 1
    Unenhanced CT scan

    Large hypoattenuating mass occupying almost the entire left lobe.

     
    Area of Interest: Liver;
     
     
  • Figure 2
    Arterial phase CT scan

    Small central enhancing foci within the low density mass.

     
    Area of Interest: Liver;
     
     
  • Figure 3
    Venous phase CT scan

    A more globular central enhancement is seen.

     
    Area of Interest: Liver;
     
     
  • Figure 4
    Delayed CT scan (3 minutes)

    The mass shows more centrifugal enhancement with some peripheral unenhancing portions.

     
    Area of Interest: Liver;
     
     
  • Figure 5
    Delayed CT scan (10 minutes)

    A near total centrifugal filling of the mass was achieved.

     
    Area of Interest: Liver;
     
     
  • Figure 6
    Coronal MRI
     

    Partially exophytic large hyperintense mass predominantly arising from segments IV and V on T2-weighted images.

     
    Area of Interest: Liver;

    A similar centrifugal enhancement pattern is also seen on contrast enhanced MRI.

     
     
     
  • Figure 7
    Histopathology microphotograph
     

    Dilated venous spaces are filled with blood. Hepatocytes can be seen in the right lower corner.

     
    Area of Interest: Abdomen;

    Dilated venous spaces filled with blood.

     

    Dilated venous spaces lined by flattened endothelial cells.
