Testicular lymphoma. Transverse ultrasound image of the left testis (A) shows a large, poorly defined hypoechoic lesion (arrows) replacing most of the normal parenchyma. The color Doppler image of the left testis (B)—portrayed in black-and-white—shows markedly increased vascularity within the solid mass. The transverse image of the right testis (C) shows the same infiltrative appearance and global testicular enlargement according to the transaxial measurement, 5.45 × 4.15 cm. The color Doppler image (D) again shows marked hypervascularity. Source: Diagnostic Imaging, Pediatric Endocrinology and Inborn Errors of Metabolism, 2e Citation: Sarafoglou K, Hoffmann GF, Roth KS.
