Retrocaval lymphadenopathy mimicking tumor thrombus in the inferior vena cava.
The preoperative assessment of many renal and adrenal tumors includes evaluation for tumor extension into the inferior vena cava. Computed tomography (CT) can allow the noninvasive diagnosis of tumor thrombus but specific pitfalls related to incomplete mixing of opacified and unopacified blood limit its utility. We report another pitfall, that of retrocaval lymphadenopathy mimicking tumor thrombus in the inferior vena cava.
