“…While the reported incidence of varicocele in renal cell carcinoma varies from 0.6 to 11.4%, the association of an isolated right varicocele and renal tumors is sparsely documented [5]. Various mechanisms have been described for the formation of right-sided varicocele in association with renal cell carcinoma such as extension of tumor thrombus into the spermatic vein with or without thrombus extending into inferior vena cava, invasion of right renal vein by the tumor causing dilatation of the gonadal vein and obstruction of inflow into duplicated testicular vein due to renal vein thrombus [6][7][8][9]. In the present case of right varicocele is caused by RCC without any involvement of tumor thrombus in IVC, right renal vein, right testicular vein and/or without any IVC compression by the tumor.…”

Background The presence of unilateral right-sided varicocele hints at a serious retroperitoneal disease such as renal cell neoplasm. Such tumors are usually associated with a thrombus in renal vein or spermatic vein. We report a rare presentation of right-sided renal tumor causing right-sided varicocele in the absence of thrombus in renal vein and spermatic vein but due to an anomalous vein draining from the tumor into the spermatic vein as demonstrated by computed tomography angiogram. Case presentation A 54-yr-old hypertensive male presented with unilateral grade 3 right-sided varicocele and no other signs and symptoms. Ultrasound examination of his abdomen showed the presence of a mass lesion in the lower pole of right kidney. Computed tomography confirmed the presence of right renal mass, absence of thrombus in right renal vein or inferior vena cava. The angiographic phase of CT scan showed an anomalous vein from the tumor draining into the pampiniform plexus causing varicocele. Conclusion The presence of right-sided varicocele should raise a suspicion hidden serious pathological retroperitoneal condition, renal malignancy in particular, and should prompt the treating physician to carry out imaging studies of the retroperitoneum and careful study of the angiographic phase of the CT scan can ascertain the pathogenesis of the varicocele.

“…Varicocele, which is defined as an abnormal venous dilatation and tortuosity of the pampiniform plexus, occurs more commonly on the left side 1 . Although the majority of varicocele have a non‐pathological etiology, acute nontraumatic varicocele especially in older patients and tense varicocele in supine position may indicate the presence of a retroperitoneal mass especially renal cell carcinoma 2 . Other causes include retroperitoneal sarcoma, retroperitoneal fibrosis, and lymphoma 3 …”
