case_images: Doppler ultrasound imaging. (A) Ultrasound showed huge occupation in the liver, with uneven internal echoes, and morphological under-rule. (B) The normal liver tissue in the right lobe of liver.

case_images: fig1
case_images: The liver showed inhomogeneous echogenicity, with only a small amount of normal liver tissue remaining in the right lobe (Figure 1).
case_images: Computed tomography imaging. (A) The arterial phase showed the irregular patchy foci of enhancement. (B,C) The portal venous phase expressed the range of enhancing gradually increases. (B) The left portal vein branch was extremely thin and the right portal vein branch become thinner. (C) The main portal vein in hepatic hilar region was slightly narrowed. (D) The delayed phases showed uniform enhancement of most of the lesion and patchy low-density shadows in the lateral side of the left lobe.

case_images: The portal vein was slightly narrowed by compression, there was no significant dilation of the splenic vein, and no significant splenomegaly (Figure 2).
case_images: Magnetic resonance imaging. (A) T1-weighted image. (B) T2-weighted image. (C) Apparent diffusion coefficient image. (D) The coronal MRI revealed enlarged liver occupying nearly the entire abdominal and pelvic cavities.

case_images: fig3
case_images: T2-weighted and diffuse-weighed images, and locally hypointense on the apparent diffusion coefficient map. The left lobe exhibited local streaks with even lower T1 and even longer T2 signals, with streaks of hypointense segments within. The lesion had clear margins, measured 35.1 x 32.1 x 14.1 cm, and partially protruded from the liver contour, compressing the surrounding structures (Figure 3).
case_images: Pathological image. Histological section showing that the lesion consisted of cystic dilated vessels of variable size, with large and irregular lumens and uneven wall thickness, and were lined with flattened endothelial cells with no cellular heterogeneity. (A) The low magnification. (B) The higher magnification.

case_images: Histopathological analysis revealed that the lesion consisted of cystic dilated vessels of variable size, with large and irregular lumens and uneven wall thickness, and were lined with flattened endothelial cells with no cellular heterogeneity (Figure 4).
