case_images: Abdominal ultrasonography, however, showed multiple oval lesions, up to 35 mm in size, with mixed high and low internal echoes in the liver on this admission (Fig. 1).
case_images: Computed tomography (CT) findings over time. CT on admission showed an ill-defined large tumor (arrows) adjacent to the umbilical portion of the portal vein and a small lesion (arrowhead) near the liver surface (a). CT 3 (b) and 12 months (c) after biliary drainage showed marked and complete regression of the tumors, respectively.

case_images: Although follow-up computed tomography (CT) after coronary artery stent grafting taken 2 years before showed no marked findings in the liver, enhanced CT showed multiple low-intensity lesions in the liver (Fig. 2a). EHE of the liver (Fig. 3). The patient was discharged on hospital day 31 due to the full recovery from the jaundice with the biliary drainage. Enhanced CT 2 months after discharge showed complete disappearance of small EHE lesions and marked shrinkage of large EHE lesions (Fig. 2b). Follow-up CT taken 12 months after the biliary drainage showed complete regression of the liver EHE lesions (Fig. 2c).
case_images: Pathological findings. a Hematoxylin and eosin staining showed atypical epithelioid endothelial cells arranged in hyalinized stroma. Some cells exhibited intracellular vacuole (a, arrow). Immunohistochemical staining showed positive cells of CD31 (b), TFE3 (c), and vimentin (d).
