47-year-old man with left testicular swelling. Sagittal color Doppler ultrasound image of the upper pole of the right testicle demonstrating that the well-defined hypoechoic lesion in the upper pole of the testicle has slight increased peripheral vascularity. Sagittal Color Doppler ultrasound image of the right testicle shows slightly increased vascularity between the epididymal head and the upper pole of the testicule. No significant epididymal hyperemia is noted.

Images demonstrated the presence of a 1.3 x 1.0 x 0.9 cm, well-defined predominantly, hypoechoic lesion in the upper pole of the right testicle (Fig. 1).

Images of the upper left scrotal sac and distal inguinal canal demonstrated a serpiginous 3.0 x 1.8 cm structure with heterogeneous echogenicity which could not be separated from the left spermatic cord (Fig. 2).
47-year-old man with left testicular swelling. Sagittal ultrasound image of the upper left scrotal sac and distal inguinal canal just superior to the upper pole of the left testicle demonstrating a serpiginous 3.0 x 1.8 structure with heterogeneous echogenicity that cannot be separated from the spermatic cord. No evidence of peristalsis on the real time scanning.
