J. Rubiobriones et al., INCIDENTALLY DETECTED RENAL ANGIOMYOLIPOMA WITH TUMOR THROMBUS INTO THE INFERIOR VENA-CAVA, Scandinavian journal of urology and nephrology, 31(2), 1997, pp. 189-191
A right-renal angiomyolipoma with tumour thrombus into the inferior ve
na cava was incidentally detected. This is the ninth published case of
its type and the second incidental case. Presence of a thrombus does
not imply invasive disease, but the tumour then is often bigger than 6
cm and radical surgery is mandatory.
