Dear Sara: >We recently had a 3 year old female ferret turned into the shelter. She >had an adrenal tumor frozen on July 18 of last year, and she has a >slightly swollen vulva now. Should the symptoms have subsided by now? >Or is this likely to be a recurrence or the other gland acting up? Yes, I believe that six months after surgery, all clinical signs should be gone if the surgery was a total success. There are two possibilities here - that the other adrenal gland has a functional lesion (approximately 15% of adrenal cases are bilateral), or that the previous adrenal was not completely removed. Without knowing what type of tumor was removed - it could either be that a benign tumor was incompletely frozen, or that a malignant tumor was incompletely removed and has shown regrowth. It looks as if that another surgery may be in the offing - let's do it early while she is an excellent candidate. With kindest regards, Bruce Williams, dVM [Posted in FML issue 3300]
