I just received a CT scan report and there is a mention of an 8mm hypodensity in the midpole of the right kidney is of fat attenuation. what does this mean? I have an incision that goes from under the breast down past the naval and I have lumps that have formed on either side of the incision. Sometimes they are painful and I have been told it's scar tissue. Could this fat attenuation be a result of the scar tissue?
