Hi, my rabbit had an ultrasound done on Sunday that revealed a mass, the vet initially suspected it to be a bacterial infection and gave me penicillin injections and so far I’ve only administered it that Sunday. On Monday night she gave me a call that I had missed and left a voicemail saying that the aspiration they did showed that no bacteria was present and it was rather necrotic cells and the full report she sent over suggested to consider the mass benign etiology(abscess or granuloma) given the lack of vasculature but that she wants me to continue with the antibiotics, I wasn’t able to get a call back to ask why she would want me continuing antibiotics if there is no bacteria present and she will not be back in office until Friday. I don’t feel comfortable continuing to give antibiotics without knowing what it’s doing if there is no bacteria to be killed. Is there any reason why antibiotics should be continued if there is no bacteria present which was the initial suspicion and the sole reason antibiotics were given. She also wants me to get a CT scan done to determine where it’s coming from and to see if the can surgically remove it, the ultrasound showed that the mass isn’t attached to any organs or intestines and that it is a mobile and encapsulated mass. The cost for a CT scan is probably another thousand alone if not more and I’ve already spent thousands for the ultrasound and biopsy and it feels like she just keeps pushing for more and more.
