Mature teratomas, prepubertal-type: ultrasound appearances. a, b Ultrasound and colour Doppler of a 10-month-old boy with a swollen and tender left testis show an avascular cystic mass completely replacing the testicular parenchyma, an orchiectomy being required. Right testis (discontinuous arrow). c, d Ultrasound and colour Doppler of a 8-month-old boy with a painless scrotal left mass show a mixed solid-cystic mass (arrows) without blood flow in the solid part of the lesion. Orchiectomy is practised because of the big size of the lesion. e, f Ultrasound and colour Doppler of a 8-year-old boy with a swollen and hard right testis show a heterogeneous solid mass, calcifications (arrow) and blood flow inside. A testis sparing surgery is practised since sufficient salvage parenchyma is visible
