Fat Deposit in Upper Abdomen After Tummy Tuck

I had a full tummy tuck and muscle repair with no lipo . Im quite slim (90lb, 5"2) but have noticed a bulge in my upper abdomen which gets worse after eating. My doctor says that muscle was repaired to the top and that the bulge is a fat deposit. He said he could do lipo to that area but it still wont be totally flat He and that he could tighten a bit more but that the bulge would just move higher as that is a small amount of fat on my stomach cavity. what can i do for my upper abs to be flat? Have attached the results of the ultrasound of my upper abdomen.
