What Does The Following Body Scan Report Indicate?

Question : I recently had a full body scan to look for possible lytic lesions, x-rays from head to toe.
I had some slightly abnormal lab work, normal kappa, low lambda and an elevated K/L ratio of 2.51. I had been on Leflunomide for rheumatoid arthritis for 8 months. All other lab tests were normal except my gamma globulins are low. They are in the process of doi ng Igg tests and others. I do not have copies of the actual x-rays yet. However, I received the radiologist report today and was wondering if you could explain which bones are involved..I think it is only one but I'm not sure. It states "there is a 5 x 3 mm lytic lesion involving the right radius distal metaphysis and proximal left femur shaft". Is this both the wrist and leg or just the leg? I was in a pedestrian vehicle car accident and fell very hard (slammed to the pavement) on my buttocks and back. I know lytic lesions can mean cancer but they can also be benign. Could one happen from a significant trauma? Please share your thoughts with me based on the information I have given you. Do not ask for the x-rays as I do not have them yet.
