Thank you for all your thoughts. The result is as we thought but we don't necessarily have to lose him yet but we will probably have to say goodbye to him this year
Emrys has a thymoma in his chest, the mass is fairly large and is impacting on his trachea and esophagus. This explains his decrease in appetite and activity. The pressure put on his trachea means he cannot get enough breath, and he is breathing at a slightly faster rate. However there are no other growths throughout the body, and because the thymoma is not impacting upon the heart (though near it) or lungs, this would suggest a slow growth. Therefore the vet feels it prudent to try him with some medication to lower the blood pressure. The presence of the tumour has led to an increase in blood pressure hence the bulging bloodshot eyes. The tumour has also led to some excess fluid in the abdomen and this also causes raised blood pressure. Though near but not touching the heart, it is bearing down on his arteries. Without a biopsy it is hard to tell which part of the mass is malignant. It will continue to grow and the cancer may be in the wall of the mass or the centre. That would mean it is either a carcinoma or a lymphoma. It is fairly rare in rabbits round here (he last had a case in 2007) and just bad luck. The thymus gland ought to disappear at or near birth, if it doesn’t it can become a growth site in later life.
Also Emrys cannot see because there is no light getting into his retinas due to the bulging and pressure. So we have come away with some medication (Fortekor and Furosemide) to reduce the blood pressure and fluid build up. The idea is to bring Emrys back down to a stable state, where he can maybe regain some sight. He is quite bewildered and asking for attention and seeking comfort from us because I think he is anxious, scared and does not understand what has happened. So although we will have to lose him, we hope to do so on a high note, where he is feeling better within himself, feeling more normal and confidant. He is currently not in pain but is probably feeling some pressure around the eyes and head so there will be discomfort. But I have expressed to the vet that I do not want to prolong any suffering or keep Emrys alive for my own safe. We are going to try the medication for a week or so to see if it helps at all and we are also due back for a check up next week. Emrys' response to the medication will very much dictate how we next proceed, so its one day at a time for now.
Tonight he is quite groggy and unsteady due to the GA. Understandably he is reluctant to eat but is keen to drink and he has eaten some soft fresh dandelion leaves. I am hoping to disguise his tablets in a raisin (don't worry he won't get too many per day) as it worked for another rabbit when she had a stroke.
My vet kindly let me take a picture of the x ray plates and I also have some pictures of Emrys from tonight. I think I will post in the photos section so that more members can become aware of what a thymoma is.
Thank you for all the support, it means so much.
if he responds to the medication then the bulging should go down and he should be able to see again, the idea is to give him some more time at a more comfortable status.
