case_images: Contrast-enhanced CT image in portal phase (A) shows rounded, non-enhancing cystlike lesion (arrows) in liver segment five, with fluid-fluid level (arrowhead) on unenhanced CT image (B).

case_images: On contrast-enhanced CT, there were rounded, non-enhancing cystic lesions in liver segments four, five, and seven (Figure 1).
case_images: T2-weighted (A) and unenhanced T1-weighted MRI (B) show a round, well-defined cystic lesion in liver segment five (arrows) containing fluid-fluid level (arrowheads). There is no evidence of contrast enhancement from arterial (C) to delayed phase (D), and with signal defect on hepatobiliary phase imaging (E).

case_images: On gadoxetic acid-enhanced MRI, none of the lesions showed contrast enhancement, and there were signal defects on hepatobiliary phase imaging (Figure 2).
case_images: (A) B-mode ultrasound with MR fusion guidance shows a solid homogeneous hyperechoic lesion in liver segment five (arrows). On contrast-enhanced ultrasound, (B) portal-phase image shows peripheral nodular contrast enhancement (arrowhead), and complete fill-in and without washout on delayed-phase (C).

case_images: CT or MRI findings, ultrasound revealed that all lesions appeared solid with homogenous hyperechogenicity. CE-US revealed very slow peripheral nodular enhancement and complete fill-in, and without washout on delayed-phase (Figure 3).
