Genitourinary Radiology > Male Pelvis > Testis > Varicocele



A varicocele is distension of the pampiniform venous plexus due to incompetent valves of the spermatic vein. Standing or valsalva may provoke the distension. 95% are left-sided, and are the most common manageable cause of male infertility. The compressible, tortuous vessels measure more than 2 mm diameter.

Ultrasound demonstrates multiple serpiginous anechoic spaces of similar size, and Doppler shows venous flow within these spaces.

MRI reveals multiple serpentine vessels in the left hemiscrotum.

Gray scale (1, 3) and color flow (2) images of both paratesticular tissues shows bilateral serpiginous structures with color flow demonstrates in close associated with the spermatic cord consistent with bilateral varicoceles.
