OK, HERES THE DEAL...THIS WILL BE LONG TO GET THE HISTORY ALL HERE. I HAVE AN 11 YR OLD ARAB MARE, ALL HER LIFE SHE HAS BEEN A LITTLE STUDDY ACTING AT TIMES, BUT HAS BEEN OK,HAS CYCLED REGULARILY, SHOWED NORMAL HEAT SIGNS AND BEHAVIORS. OVER THE LAST 5 YEARS SHE HAS GOTTEN ANXIOUS, AND NERVOUS, NOW SINCE SPRING SHE HAS GOTTEN POSSESIVE OVER HER MOM AND FOAL(BROTHER), AGGRESSIVE TOWARDS OTHER HORSES IN THE PASTURE, NEW HORSES AND TERRITORAL WITH THE BARN. SHE HAS BEGUN LIP CURLING WHEN SHE SMELLS POOP OR URINE AND HAS NOT CYCLED AT ALL THIS YEAR, OR T LEAST HAS NOT SHOWN, WHEN I TAKE MY OTHER MARE OUT SHE WILL WHINNY AND NICKER LIKE A STALLION WHEN I TAKE HER OUT AND WHEN I PUT HER IN. SHE WHEN BEING RIDDEN BITES MY (OR ANYONE ELSE RIDING HER) LEFT FOOT, NOT AGGRESIVELY, MORE LIKE SHE IS TRYING TO MOVE IT, AND LOOKS TO HER LEFT SIDE LIKE THERE IS EITHER SOMETHING THERE OR PAIN, NEVER THE RIGHT JUST LEFT, WHETHER BAREBACK OR SADDLE, PAD AND GIRTH MAKE NO DIFFERENCE. SHE HAS BECOME VERY PHYSICALLY IN HTE LAST YEAR "FIRM", HER NECK AT THE EARS AND CREST, AND IN FRONT AND BELOW THE WITHER, HER SIDES OF HER RUMP BELOW HER HIP BONES. IN HTE PASTURE SHE WILL EXTEND FULLY, BUT WHEN BEING RIDDEN SHE IS VERY UNDERNEATH HERSELF AND SHORT STEPPING LIKE A PASO FINO LOOKS BUT IS NOT LAME AT ALL! SHE IS WILLING AND LISTENS BUT IS VERY QUICK SHORT STEPPING, NOT ROUGH OR CHOPPY. SO MY QUESTION IS ... THE VET WILL BE OUT IN TWO WEEKS TO PALPATE AND US TO CHECK FOR AN OVARIAN CYST, AND HE SAID THE ONLY TREATMENT IS SURGERY TO REMOVE THE OVARY ADN CYST AND THAT HER BEHAVIORS SHOULD CORRECT THEMSELVES IN 6 MONTHS TO A YEAR. IS THIS CORRECT? AND WHAT ARE THE RISKS OF SURGERY AND NOT DOING SURGERY????? DO ALL THESE THINGS I HAVE WRITTEN ABOUT SOUND LIKE SYMPTOMS OF A MARE WITH A CYST?
I suspect you mean "tumour" not "cyst" and what has been suggested to you is the possibility of a granulosa thecal cell tumour (GCT). Follow that link and you will find an article on this site that should answer a lot of your questions. Make sure that the diagnosis of a GCT is based upon blood assays rather than a palpation or ultrasound. Typically an inhibin and testosterone assay is used.

Thank you Jos for the correction! I do believe that is what he said, so I cannot rely on a u/s or palp, what type of blood tests am I going to need to request? Any info I have to request testing the better to try to decide what it is and what to do about this mare. So if that is what it is and I opt to not do surgery due to finances what am I looking at as far as behavior and health? again any help is greatly appreciated! My vet is not a repro specialist, so I am not sure if he knows all he will need to do, I would hope so though!

well I had this mare checked today, she was showing signs of colic, but wiht a fever, and when he went in rectaly he didnt even need to look, he was able to feel this large mass, so he did an U/S and what he found is not good! On her left side she has a large mass with several large follicles ranging from 30 to 54mm, and several small ones he did not measure as well as some kind of fluid. On her right side she has several small follicles and a few larger ones with the largest being 31mm, He suspects that she has the granulosa cell tumor on her left, and as rare as it seems on her right as well. SO JOS, what am i looking at here? He did a blodd work up, cbc and something else. Is this a bad case, what are the chances for successful removal, what are the risks of removing or not removing. this mare is 11 years old. I am just torn up, i am not sure i can or want to put 2000.oo+ into this horse, she is a grade arabian that has anxiety problems so she cannot be shown, however she is broke to death and is as sweet as sugar as long as there is no new horses around, however i do not know if i can let her be knowing this too!!! I am not sure if her behavior/anxiety would change if she had surgery... JOS do these usually cause any pain to the horse? (like during riding, leg raised for hoof trimming or anything?) HELP!!!!!!!!!!!!!!! I DO NOT KNOW WHAT TO DO!!!! ANYONE WITH INPUT IDEAS OR HAVE BEEN THROUGH THIS HELP!!!!!

You are at the time of the "fall transitional stage" (assuming you are in the northern hemisphere), and as such, you will see ovaries that look the same as spring transitional phase - multiple follicles, some may be large, and a higher percentage of incidences of annovulatory hemorrhagic follicles will commonly be seen. These AHF's can look - per ultrasound - very similarly to what a GCT looks like per ultrasound. Ultrasound therefore is not a good medium for a definitive diagnosis of a GCT. On top of that, in the case of a GCT, it is most common to see the contra-lateral (the opposite ovary to the one with the GCT) with no follicular activity and typically flaccid (soft). It would be unusual to see follicular activity in such a situation.
I would strongly recommend that you do not do anything drastic (like removing ovaries) without doing some further diagnostic work! Blood assays for testosterone and inhibin levels are typically used to confirm presence of a GCT. If your veterinarian is not familiar with these tests (or any of the above items), or is not recommending them prior to removal of the ovary(ies) I would personally want to seek a second opinion from an equine reproduction specialist before doing anything else.
Looks like I'm in this boat now. History: 5yo Oldenburg mare. I've had her 2yrs. Bought her from my trainer who tried to breed her 4X unsuccessfully prior to my purchase. Always thought she didn't get pg due to young age etc... She's been in full dressage training for 2 yrs. Always been a strong minded girl. However, she does rear. At first we thought it was a training issue. However, now after a very thorough exam we've discovered cysts (my vets words) in the ovaries. 5 of them. Trainer wants to take ovaries and go from there. I always planned on breeding her, so want to take it slowly. Vet is taking blood and sending it up to Davis. What now? What can I expect? Trainer doesn't want to ride her until issue is solved. I really don't want to do anything drastic, but I want everyone to be safe! Thanks for your help. Between a rock and a hard place.
Cysts on the equine ovary are unusual. I think I might want to get more diagnostic work done by a specialist before doing something as drastic as removing ovaries - once they're out you can't put 'em back!
If your trainer is suggesting that the behaviour problem might be related to estrus ("heat") you should also be aware that once you remove the ovaries the mare is not going to resist stallion advances like a diestrus mare would, and in fact may display estrus continuously.
I have a 13 year old Arabian Mare, I have tried unsucessfully to get her pregnant 3 times. The last time being almost perfect for conception. We bred her within 6 hours of ovulation per U.S. My question is if it's an Immune problem using any of your protocol's wouldn't help getting her pregnant? Correct me if I'm wrong??? Another thing that I noticed was about the 6th day on all post breedings she gets this weird thing going on, where she looks just like a mare in labor, laying down, getting up, walking around in circles and still eating slightly, also doing this stretch thing. It's not colic after about a few hours it's gone she is back to normal! Jos do you think it's EED???
PPPPPPPLLLLEASE HELP me I'm desperate!!!!!!!!!!!
Jos thanks for all your appreciated information I always look forward to your posts.
There is a vast list of things that could cause a mare to not become pregnant or not maintain a pregnancy. By "immune problem" I'm assuming you mean a stallion/mare incompatability? If so, that - although a possibility - would be well down on my list of likely causes.
EED does not manifest as colic-like symptoms (or any outward symptoms come to that).
Your best bet without a doubt is to take her to an equine reproductive specialist - preferably a theriogenologist. It's often cheaper in the long run, and a lot less frustrating!
Jos- I really appreciate your help on this. The thought process on removing the ovaries is that they are causing her pain and hence the rearing. Is it a wives tale that these cysts cause pain and hence the rearing? Trainers worry is if they're removed once they'll return and I'll have the same problem all over again.
After the blood test, what other diagnostics can I ask for? THANK YOU!!
