Thanks for all your help!
Tjhe answer came from one of the most unlikely and unfortunate places places- her little sister got real unwell and it was only then we thought to do a lumbar puncture.My patient ended up getting tranferes to a hospital with a bigger PICU but the sister is at our PICU.It turned out it was slow onset bacterial menigitis.I cant believe we missed that but the symptoms where confussing.It could have been fatal .I feel so guilty for missing it.
