Renal cell carcinoma invading the right ovarian vein: multidetector computed tomography and ultrasound Doppler findings

Multidetector computed tomography (MDCT) and Doppler ultrasound findings of a renal cell carcinoma invading the right ovarian vein are presented. An MDCT study performed for evaluation of macroscopic hematuria showed a heterogeneously enhancing malignant thrombus in the right ovarian vein that was in continuity with inferior vena cava and right renal vein thrombi of identical characteristics. Further investigation with Doppler ultrasound confirmed these findings and showed arterial blood flow of low resistance within the ovarian vein and inferior vena cava thrombi. To the authors' knowledge, this is the first report of MDCT and Doppler ultrasound findings of a renal cell carcinoma invading the right ovarian vein.
