title: [Tumor thrombosis of the left renal vein and inferior vena cava secondary to renal cell carcinoma. Findings with ultrasonography, Echo-Doppler, and computerized tomography].
abstract: Renal cell carcinoma represents a 2.5-3% of all neoplastic processes, usually seen un patients older than 50 years. 60-75% are resectable at diagnosis, representing local or metastatic advanced disease the rest of them. This tumor tends to spread intravascularly, leading to tumoral thrombosis within the inferior caval vein (ICV) and renal vein 4-10% and 21-35% of cases, respectively. As the only effective treatment is surgical resection, preoperative determining of the thrombus extension is crucial. Thus, an accurate radiological study including ultrasound, doppler sonography, computed tomography and/or Magnetic Resonance, is key for these patients. We present a 49 year-old patient with renal cell carcinoma and associated tumoral thrombosis in inferior caval vein and left renal vein; we provide the most significant figures, explaining its most characteristic radiological findings.
