Lymphoma can't be diagnosed by visual inspection, even with ultrasound. It can only be diagnosed by cytology. I'm not saying those masses are *good* news, but I am saying that there is no way to know that they're lymphoma by ultrasound alone. Did your vet take any kind of tissue samples? I suspect not since Monday is a little soon to be getting pathology results for a Thursday exam. At the very least he will need to take fine needle aspirates and send those to a lab for cytology. Sometimes even aspirates aren't conclusive for lymphoma either, and a full biopsy is needed instead. Don't give up hope yet. There's a lot more work to be done before you can definitely call this lymphoma. In fact, in Pete's case I would be FAR more likely to suspect adrenal disease, based on your description. I would not be at all surprised to hear that this is Cindy's problem, too. Adrenal disease will cause one or both of the adrenal glands to swell to where they show up on ultrasound as you described. The way Pete is straining to pee is highly characteristic of adrenal disease (in males) too. Watch him *carefully*. If he stops peeing altogether you will need to get him to a vet as soon as possible, basically within 24 hours, to have his bladder drained. Discuss this with your vet. Ask about doing more tests, especially aspirates and pathology. Mention adrenal disease to him and see what he says. If your vet is reluctant or refuses to do more work, find another vet as soon as you can. Don't be afraid to get a second opinion from another vet anyway. I strongly suspect that neither of these babies has lymphoma. There's no reason to let something that is easily dealt with, like adrenal disease, take them because of a misdiagnosis. I'm not a vet; I just visit mine far too often. roger & the wolverine wannabees missing bear and lancelot [Posted in FML issue 4238]
