Thank you so much for your insights.
The ultrasound report came back and he has a mass in the mesentery of the intestine measuring 8x8x4 cm (3"x3"x1.5") and they are guessing it's liposarcoma, a rare cancer of soft fatty tissue - slow growing (a type of soft tissue sarcoma). Less likely would be infiltrative lipoma, and less likely than that is dilated lymphatics of edema (which I assume is similar to lymphangiectasia / PLE). Perhaps the PLE is what is what is causing his 12 weeks of diarrhea, which is pure liquid in the last 2 weeks.
We would need an oncologist aspiration or biopsy to find out for sure and then perhaps surgery. We don't want surgery for him given how big the mass is relative to his body size, his age (12) and his declining health/weight.
This thread has been so useful and I managed to read up some old threads, and some written by ladyjane with regards to lymphangiectasia/PLE. I might try to request prednisone to stop the diarrhea. I stopped the Fortiflora, Metronidazole because when I gave it with a painkiller Gabapentin- he vomitted twice in a day and the same day he couldn't stand on his feet for a few minutes until I steadied him with my hands. Right now he isn't on any medications or probiotics (Fortiflora) and seem better than when he was on it. Getting him to eat is quite a feat now and we have to try different things every day, mostly bland human food. Perhaps I should try Royal Canin Gastro Low Fat kibble? He is not eating his kibble.
He is so skinny, you can feel bones everywhere. His liquid diarrhea persists. He had half his teeth pulled out 2 years ago and given his age, probably has some dental issues. Sub-q fluids might be an option as well.
If anyone experience dealing with any of these issues, would really appreciate your input. I feel like 12 is too young and he has some years left. I'm heartbroken. It's so hard. |
