I found the same thing as xmdmom - but I also looked them up separate "lymphoid" and then "hyperplasia".... I do not remember if they ever put a name to it, but when I read them separately it sounds like what my son had when he was first diagnosed. He was actually have a lot of pain in his abdomen near his liver area. So they decided to do a sono and that led to a variety of other tests. In the end all was well, it just showed his body was fighting off infection/bacteria? from the Crohn's - and he got some really good tests along the way. Scary going through the tests, nice to know it was normal for him.
Still worth getting clarification from the doctors... I hope there the rest of the labs were good!
