ct results/possible lesions...

[happymom2v]

Can someone help me understand this results of a CT scan with contrast.
There is a 4.0 cm cyst in the inferior pole the left kidney. FYI...the 4.0cm cyst has been present for many years.

The other finding is "few other sub-centimeter low-attenuation lesions in both kidneys are too small to characterize. What does this mean??? Should we worry?

Thank you Caryopteris.

But... The other finding is "few other sub-centimeter low-attenuation lesions in both kidneys are too small to characterize. What does this mean??? Should we worry? What does low attenuation mean???

This does not sound like cancer or anything to worry about.
