A: CT scans in the arterial phase shows a mass with rim arterial-phase hyperenhancement (arrows); CT scans in the portal venous (B), and delayed (C) phases demonstrates gradual enhancement of the mass (arrows); C: there is also heterogeneous hyperenhancement in the delayed phase; D: CEUS in the arterial phase shows irregular rim arterial-phase hyperenhancement in the mass (arrows); E: CEUS at 48 s after contrast injection demonstrates early washout (arrows); F: CEUS at 115 s shows marked washout (arrows). CEUS: contrast enhanced ultrasound
