To Lindy Garner: >Does this mean the right adrenal gland probably has a tumor??? Her left >is gone (so the vet says)... Well, it certainly looks like it, unfortunately. About 15 percent of adrenal lesions are bilateral - meaning affecting both adrenals. You can try the adrenal panel at the Univ. of Tennessee (see the medical FAQ for phone number, etc.) before you subject her to another surgery. This will tell you if there is elevated levels of estrogens or pre-estrogens which are causing her problems, and whether another surgery is needed. Although it is a bit on the pricey side ($75 to your veterinarian), it will make sure that Idgie doesn't go through an unneccessary surgery (very important when we only have one adrenal to start with.) However, whereas we used to never remove the second adrenal, the last two years have seen improvement in surgical techniques to remove part of the remaining adrenal, and, if needed, a replacement protocol for steroids should the entire remaining adrenal need to be removed.
