2-year-old male with a presacral yolk sac tumor developed multiple FLL’s while on therapy. (A) Coronal contrast enhanced CT image shows two well defined hypodense lesions (arrows). (B) Arterial-phase CEUS image obtained at 10 s after contrast administration shows two hypoenhancing lesions (arrows). (C) Portal-venous-phase CEUS image obtained at 31 s after injection and (D) delayed-phase CEUS image obtained at 2 min and 14 s after injection again show hypoenhancement of the lesions (arrows). These were pathologically proven to be abscesses with necrotizing granuloma
