Unilateral scrotal discomfort in a patient with known renal agenesis: do not forget about Zinner syndrome

Abstract

The scrotal US scan showed a thickened and inhomogeneous, hypoechoic left epididymis (figure 1A) with normal vascularisation at Doppler imaging (figure 1B), findings consistent with ejaculatory duct obstruction. Both testicles were normal for size, echotexture and vascularisation; no significant hydrocele or varicocele was found; scrotal walls were normal. The additional use of a convex probe showed a left periprostatic cyst-like structure.
