    Plain CT image showing a hypodense mass with central coarse calcification in the left liver lobe. Ascites is also present.

     
    Area of Interest: unknown; Imaging Technique: Helical Computed Tomography Studies;

    Arterial dominant phase of the dynamic study. The main tumour mass displays heterogeneous enhancement mainly at the periphery. Another small lesion with similar enhancement properties is detected on segment 4....

    On this T1 - weighted image (TR/TE=680/25ms) the tumour is hypointense with a more hypointense central scar. The additional lesion at segment 4 is spontaneously hypointense.

     
    Area of Interest: unknown; Imaging Technique: Magnetic Resonance Imaging Studies;

    T2-weighted image (TR/TE=2100/90 ms) reveals the heterogeneous tumour at the left liver lobe almost isointense to normal liver parenchyma. The central scar remains hypointense. Lesion at segment 4 is not apparent.

     
    Area of Interest: unknown; Imaging Technique: Magnetic Resonance Imaging Studies;

    T1-weighted image (TR/TE=620/25 ms) obtained 6 minutes after a bolus injection of Gd-DTPA. The central hypointense scar did not enhance during the early phase of contrast administration (not shown) or during this...

Arterial dominant phase of the dynamic study. The main tumour mass displays heterogeneous enhancement mainly at the periphery. Another small lesion with similar enhancement properties is detected on segment 4. Enhancing lymphadenopathy is also depicted adjacent to the inferior vena cava.
