Recent lumbar ct revealed small cortical based density posteriorly upper to mid right kidney measures 1 cm and is isodense to adjacent renal cortex. I was told to make appt with urologist. I did and told nurse what was on ct. They seemed quite concerned. They have now scheduled an ultrasoung, appt with urologist and general surgeon. I am a little anxious being that the final impression does say he could not rule out a mass lesion. I used to precept so I know what that means. Why am I scheduled with a surgeon and do these findings pretty much indicate rcc?
