Retroaortic left renal vein in testicular cancer patient: potential staging and treatment pitfall.
A 20-year-old man was diagnosed with a left mixed germ cell testicular tumor and clinical staging with computerized tomography suggested left para-aortic subhilar retroperitoneal adenopathy. The patient received 4 cycles of cisplatin, vinblastine and bleomycin chemotherapy but the mass in the left renal hilus area remained unchanged. Subsequent retroperitoneal lymphadenectomy revealed the mass to be a retroaoritc left renal vein type 2. Further confusion occurred during followup in differentiating this anomaly from recurrent neoplasm necessitating evaluation by magnetic resonance imaging. Retroaortic left renal vein represents a potential imaging pitfall in testicular cancer that may facilitate suboptimal staging, treatment and followup.
