Just heard from the vet....
Ellie's ultrasound looked good... the liver is a normal size and the adrenal glands looked good too (very unlikely it is Cushings)
He said he did see infection in the liver so the course of action is to give Ellie antibiotics for a couple weeks and re-test her blood... if the ALT numbers do not go down with the antibiotics, then they will biopsy her liver. He said there is no harm in waiting on the biopsy for a couple weeks.
I asked about cancer and he said it is unlikely.
So while I am relieved with today's results.... I shall be a bit on pins and needles for the next couple weeks... hopefully it is just an infection!
I cant wait to go get my girl at 3!
Thanks for the support y'all!
