Cat losing weight & hair: Can I diagnose a tumor without ultrasound?

You could take your cat to an internal medicine veterinary specialist for an ultrasound and/or other diagnostics to help get a definitive diagnosis. A specialist has more training then a regular veterinarian so may be able to read the ultrasound better. If you can't do that then you could try the anti-inflammatory and see if that helps. Your vet can monitor kidney function while on the anti-inflammatory. Hope she gets better soon.

Thank you for your post! I am sorry to hear Shurbee is not doing well. My concern at this age would be some type of malignancy. In older cats, one of the more common things we see in regards to cancer is intestinal / GI lymphoma. This does not always show up on blood work. I would highly recommend Shurbee get an abdominal ultrasound as the next diagnostic step. Hope this helps and feel free to contact me with any further questions / concerns

Although we can not prescribe treatment via an online method (illegal with our veterinary licenses), what i can tell you is that an ultrasound can not assess liver function. Ultrasound is just an image so it can tell you size and texture changes to organs and evaluate for masses, fluid, etc. Also the good appetite and energy level are not typical with liver failure. Your cat has elevated liver enzymes and total bilirubin but this does not always mean liver failure. I would try to get better clarification from your vet about what was seen on the ultrasound and were the other organs normal (pancreas, GI tract, etc.). More common causes of these bloodwork changes would include liver/biliary infection, pancreatitis, and underlying GI disease associated with the above. Cancer and certain infectious diseases such as FIP can as well. So options would include additional testing to search for a cause (such as pancreatitis testing, liver aspirates, etc.) and/or symptomatic treatment can be attempted for pancreatitis, liver infection, etc. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

I am so sorry to say but these x-rays are highly suggestive of an intestinal tumor. I would have an ultrasound done next to confirm and then go forward with treatment for suspected intestinal lymphoma, especially if she is symptomatic (i.e. vomiting, decreased appetite, etc). I wish you all the best moving forward with Fluffy. Best wishes and take care.

Without a full history and physical exam report it is difficult to know why they are recommending an ultrasound which is usually used to track changes in size or texture of internal organs, fluid build up and/or tumor growth. I recommend you contact your vets office and speak to the particular vet involved in order to get a better understanding of exactly what they are trying to identify or rule out and this will allow you to make a more informed decision as to the risks and benefits of anesthesia for an older cat with evidence of kidney issues. A full assessment of the entire blood work and any other current symptoms would be needed to discuss in any more detail and your vet should release these to you for a second opinion should you not feel the situation is adequately explained when you speak to them directly

I'm sorry Murray isn't doing well!! Unfortunately with his symptoms cancer could be a likely diagnosis. Other causes could be a foreign body or intussecption (where the intestines telescope into themselves), but without seeing him in person I can't say for sure. Next step would be x-rays to try to visualize the intestines or an ultrasound. I recommend speaking to your vet about doing these tests.

Poor Sachi! Significant weight loss and inappetence are certainly a major concern. I'm glad to hear that his blood work (I assume a CBC, chemistry and T4?) was unremarkable. However, foreign body intestinal obstruction/blockages, intestinal malabsorption issues that can cause inflammatory bowel disease (IBD) or exocrine pancreatic insufficiency (EPI), chronic pancreatitis, or cancerous processes, do not necessarily cause changes on screening blood tests. If Sachi has not yet had abdominal x-rays or an ultrasound, consider talking to your vet about these tests as his next diagnostic step. If he has a foreign body obstructing his intestines, this is a surgical emergency, and these tests would be helpful in obtaining a diagnosis. If pancreatitis, IBD or EPI are more highly suspected, consider talking to your vet about testing for vitamins B12 and folate, as well as TLI and fPLI. I hope this helps!
