Liver ultra sound disclosed a large mass of the segment 4 of the liver, nodular in shape, isoechoic to the parenchymal liver (Fig. 1).
Enhanced CT scan axial images (2a: arterial phase 2b: portal phase).. Pseudonodular hypertrophy of the segment 4 of the liver isointense. Normal vasculature of the liver is showed through the mass.

The patient underwent a CT scan that revealed an important hypertrophy of the segment 4 of the liver having a tumoral appearance isodense to the liver on unenhanced and enhanced CT (Fig. 2a and b).
(a) T2 weigthed MRI axial image; a mass-like segment 4 of the liver isointense to the parenchyma. (b) T2 weighted MRI coronal image; important hypotrophic left liver lobe.

T2 weighted images (Fig. 3a). The left liver lobe was deeply hypotrophic (Fig. 3b).
Arterial phase enhanced MRI; the pseudomass is slightly enhanced.

MRI with gadolinium agents, the pseudotumorous lesion was slightly hyperintense on arterial phase (Fig. 4) and iso-intense on portal one (Fig. 5). MRI showed also splenic necrotic foci areas and ascitis.
Liver ultrasonogram one year later: stable appearance of the mass.
