Double inferior vena cava (d-IVC) is a subtype of vascular anomaly that rarely needs treatment. Here, we present a rare case of d-IVC accompanied with concurrent renal pelvis and bladder carcinoma. Due to misdiagnosis, the anomalous left inferior vena cava (IVC) entering the left renal vein was mistaken as the gonadal vein and was then severed during the radical nephroureterectomy. Fortunately, the injured left IVC was recognized correctly during the following cystectomy. The vascular reconstruction operation was performed to recanalize the left iliac veins by anastomosing the ligated vascular stump to the right IVC in an ‘end-to-side’ way. During the hospitalization, the patient was treated with ‘low molecular weight heparin’ and then warfarin to ensure an ideal international normalized ratio. He recovered well from the surgery. A meticulous and comprehensive analysis of radiographic imaging is critical to avoid misdiagnosis of d-IVC.
