Fig. 1.

Abdominal ultrasonography shows hypoechoic mass with irregular margin at segment IV of liver.

Fig. 2.

Abdominal CT scan reveals 6.6×5.3 cm sized mass-like lesion with enhancing at both pre-enhance phase (A) and portal phase (B) images. Axial contrast enhanced portal phase image shows a diffusely hypodense liver (55 hounsfield units [HU]) in comparison with the spleen (110 HU) with a spared zone (segment IV).

undefined

Fig. 3.

Liver MRI. (A) Portal phase shows a lobulating, enhancing mass at segment IV of Liver. There is noted a aberrant right gastric vein in mass at segement IV of liver (arrow). (B) Hepatobiliary phase reveals high signal intensity at segment IV of liver. Diffusion weighted (C) and T2-weighted (D) images show no significant signal changes between segment IV of liver and the other part of liver.

undefined

Fig. 4.

Liver MRI. Axial T1-weighted (A) in-phase and out of phase (B) images shows an important signal drop of the liver on the opposed-phase image with the exception of spared zone in segment IV of the liver.

undefined

Fig. 5.

Microscopic findings of liver (H&E). (A) Hepatic steatosis was observed but there were noted some regions without fatty changes (×100).(B) In addition to hepatic steatosis, balloon degeneration, periportal inflammation, perisinusoidal fibrosis were also present (×200).
