Metachronous isolated inferior vena cava tumour thrombus in renal cell cancer: a rare aftermath.

Renal cell cancer (RCC) accounts for 3% of all solid malignancies. Synchronous tumour thrombus in the renal vein or inferior vena cava is reported in 4-10% cases and is a surgical challenge. Contemporary imaging modalities that are used to define the presence and extent of venous thrombus include colour Doppler, contrast-enhanced computed tomography and magnetic resonance venography. Surgical management depends upon the degree of tumour thrombus. We report isolated recurrence of RCC in the inferior vena cava 2 years after radical nephrectomy, and discuss its pathophysiology and management.
