Does combined PET-CT imaging accurately detect recurrent RCC and tumor thrombus in the renal vein and inferior vena cava?
PET-CT imaging may be useful for distinguishing between bland and malignant thrombus in patients with renal cell carcinoma.
May aid differentiation of malignant from bland thrombus in RCC; leaves open prospective validation before clinical adoption.
Thrombus of the renal vein or inferior vena cava is a known complication of renal cell carcinoma (RCC). Accurate discrimination between bland and malignant thrombus can have significant implications toward clinical management. Distinguishing between these 2 entities is not usually possible with enhanced computerized tomography (CT) or magnetic resonance imaging. This case reports the role of combined positron emission tomography-CT imaging in the accurate detection of recurrent RCC after partial nephrectomy and surgically proven tumor thrombus in the renal vein and inferior vena cava.

Rydberg et al. (2004) conducted a case report in Recurrent renal cell carcinoma with tumor thrombus (n=1). Combined positron emission tomography-CT imaging was evaluated on Detection of recurrent RCC and tumor thrombus. Combined positron emission tomography-CT imaging accurately detected recurrent renal cell carcinoma and surgically proven tumor thrombus in the renal vein and inferior vena cava.
