Child had colonoscopy done which showed some prominent lymphoid tissue in the descending colon. what does this mean?

Inflammation: Prominent lymph tissue usually signals some type of inflammation. Deciding what is causing the inflammation is the more difficult aspect here. It could be post-infectious (after a viral GI infection), could be a more systemic infection like mono, could be allergies/food sensitivities....The list goes on. Need to work closely with peds GI to determine if clinically significant and identify cause.
