Figure 1
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).
Figure 2
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).
Figure 3
(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).
