How do you diagnose an abdominal lymphoma?

My 12-year old had Epstein-Barr last year and recurrent mono for 9 months. 10 days ago she began complaining of a sharp, intense, twisting pain to the left of her belly button. The pain was so bad she had trouble walking. I took her to the ER. Her stomach was tender to the touch. A CAT scan was ordered. It was negative. The doctor suspected an injury or infection, and we went home. The pain continued to come and go, but not as severely. Yesterday the pain came back severely. I took her to the doctor. The doctor ordered blood work and some kind of scan- I think maybe a barium x-ray? She had radioactive material injected into her blood stream and they took pictures of her abdomen. The test was to look for mesenteric diverticulitis. It was negative. The blood work was also negative. No sign of any infection, and only a few abnormal white blood cells. (I asked because these abnormal white blood cells were supposed to be indications of the mono continuing the last time she had her blood drawn).

I am worried about Lymphoma because of the 9-month bought with Mono she had and the severe abdominal pain. My question is whether the CAT scan and other scan she had yesterday rules this out. If not, what does she need?

Darn, wish you could edit these posts. I forgot to add that she becomes nauseous before  the intense pain begins.

I'm certainly no expert on this but I would think the CT scan should give you some peace of mind in that I would think it would show swollen lymph nodes in her chest cavity. I have chronic EBV, I've always been worried that I will develop lymphoma. Good luck to you and I hope you get whatever is going on figured out.
