A. Longitudinal B mode image of the left testicle with high frequency (14 MHz) linear ultrasound array shows a heterogeneous ill-defined mass in the upper pole (arrows). B. Color Doppler shows no inner vascularity and a peripheral hyper vascularized rim. C. Contrast enhanced ultrasound image captured 45 seconds after the administration of 1.2 ml of microbubble contrast agent (SonoVue©, Bracco, Milan, Italy) shows total lack of enhancement of the lesion (asterisk), a hyper enhancing peripheral rim (arrows) and normal parenchymal enhancement of the lower testicular pole
