Follow-up ultrasound performed 5 days after the first examination. A-B. B mode image of the left testicle performed with a linear array high frequency transducer. The lesion remained stable in size but showed diffusely hypoechoic (asterisk) with inner isoechoic structures presenting mild color Doppler signal (C - arrowhead). On CEUS (D) (2.4ml SonoVue© performed with a curved array ultrasound transducer (8 MHz)) the lesion remained hypo vascular with central linear enhancing structures (arrow). Peripheral hyper enhancing rim persisted unchanged
