So my doctor says my liver 21cm is normal and healthy
 

Please help I went to a specialist because an unrelated CT scan showed I have an enlarged liver 21cm so my doc ordered another to confirm and ultrasound both came back normal just showed liver size and order every blood test under the sun allcame back perfect. I am 5-11 and 180lbs and fit. My doctor says I just have a healthy large liver it's like having a big nose. Is this possible or am I that special lol has anyone seen or heard of that. Thanks all
