Right varicocele secondary to left-sided inferior vena cava with a retro-aortic left renal vein and azygos continuation

Özet

Varicocele represents the main cause of male infertility. Right-sided varicocele is rare and can be due to renalmalignancy or a venous abnormality. The most common anomaly of the inferior vena cava (IVC) is interruptionof IVC with azygos continuation, which is recognized as an uncommon congenital anomaly. The prevalence of theinterruption of IVC is less than 0.3% in the healthy population. We describe the case of a 26-year-old man who hadright varicocele because of a right-sided IVC with a retro-aortic left renal vein and azygos continuation. The rightand left IVCs received the right and left common iliac veins, respectively, and the left renal vein crossed posteriorlyto the aorta and joined the right IVC. The right IVC continued cephalad as the azygos vein within the retrocruralspace. Isolated right-sided varicoceles are uncommon, but practitioners should be aware of such a condition. Incase of a venous anomaly, clinicians should aware of the association with other important clinical presentations.
