Recent advances in multidetector computed tomography (MDCT) technology enabled better visualization of testicular (gonadal) vein using submillimeter slice thickness and three-dimensional images. Normally, the testicular vein measures 1–3 mm and drains into the inferior vena cava and left renal vein on the right and left sides, respectively. They can be seen in most patients during MDCT studies. Curved planar and volume-rendered images can be used to display testicular veins. We aim to demonstrate MDCT findings of normal testicular vein and its pathologies including varicocele, varices, the testicular vascular pedicle sign, and phlebolith. The testicular vein can be dilated owing to varicocele or portal hypertension and in patients with intraabdominal seminomas arising from undescended testis. The testicular vein can also cause ureteral compression at the crossing point. Understanding MDCT findings of the normal testicular vein and its various pathologies can allow a correct diagnosis, thereby avoiding further diagnostic tests.
