The mare was presented with a previously diagnosed left-sided recurrent laryngeal neuropathy, after initial evaluation the mare underwent ventriculocordectomy and prosthetic laryngoplasty. After the procedure, the mare developed severe fluid accumulation within the surgical site, dysphagia and dorsal displacement of the soft palate. Due to severe clinical signs, a surgical revision was performed. The surgical site was drained, lavaged and a second prosthesis was placed, it was then closed in routine fashion. Following revision, the mare again developed fluid accumulation within 24 h, needle aspiration and the use of an active drain system did not eliminate the fluid production. Given the location of the surgical site and the large amount of fluid, it was suspected that trauma to the parotid salivary gland had occurred. After 10 days from the surgical revision, no signs of decrease in fluid production were observed. The mare was treated with intra-glandular botulinum toxin, and fluid production ceased 5 days post-injection. The mare was discharged from the hospital with no signs of dysphagia, dyspnoea, facial nerve paralysis, nor discharge from the surgical site 12 days post botulinum toxin injection. Follow-up performed at 7 months confirmed the absence of clinical signs, and the mare had returned to her previous level of activity.

Dwyer","doi":"10.1111/eve.14208","DOIUrl":"10.1111/eve.14208","url":null,"abstract":"<div>\u0000 \u0000 <p>A 5-year-old Oldenburg maiden mare presented for reproductive evaluation following several months of persistent oestrus-like behaviour, as observed by the owner. At referral, examination revealed anatomical abnormalities of the caudal reproductive tract, including asymmetry of the ventral labium and multiple soft tissue horizontal bands located in the vulva and vestibulo-vaginal fold. These findings raised the suspicion of an underlying disorder of sexual development (DSD). Cytogenetic evaluation via karyotyping was performed and revealed sex chromosome mosaicism. Chromosomal mosaicism is defined as the presence of two or more karyotypically different cell lines in the same individual. In this case, the mare was predominantly 64,XX, which is standard for an equine female. However, the mare also had individual cells with 63,XO (X monosomy) and 64,XY (male) karyotypes. While the presenting sign of persistent oestrus-like behaviour may have been associated with this chromosomal abnormality, a definitive causal relationship could not be established. The body of literature documenting and explaining cases of sex chromosome mosaicism in horses is limited, but the recent innovations in genetic testing have allowed for DSD to be identified more frequently and with greater ease. Recent publications have shown that mosaicism may be underdiagnosed in the equine population and can occur in phenotypically normal and fertile individuals. Therefore, mosaicism should be considered as a differential diagnosis in cases of infertility and sub-fertility. This report describes the diagnostic process leading to the identification of DSD in a mare presenting with persistent oestrus-like behaviour. It illustrates how routine reproductive complaints may have a more complex underlying aetiologies with significant implications for the horse's future working and reproductive potential. Furthermore, it underscores the value of considering DSD when investigating ‘the problem mare’ and considering karyotype as an ancillary diagnostic test.</p>\u0000 </div>","PeriodicalId":11786,"journal":{"name":"Equine Veterinary Education","volume":"38 5","pages":"e222-e227"},"PeriodicalIF":0.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147667974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Evaluating reproduction-related behaviour and performance problems in mares","authors":"S. McDonnell","doi":"10.1111/eve.70008","DOIUrl":"10.1111/eve.70008","url":null,"abstract":"&lt;p&gt;In this issue, Dr. Robert Dwyer describes a clinical case of a 7-year-old riding mare presented in early spring of each of two consecutive years for evaluation of persistent oestrus-like behaviour, intermittent aggression with herd mates and a decline in compliance during ridden work (Dwyer, &lt;span&gt;2025&lt;/span&gt;). At the time of presentation, the reproductive tract was found to be normal, with two notable exceptions: (1) vulvar asymmetry with incomplete labial apposition, and (2) two soft tissue bands connecting the left and right ventral vulva and another connecting the left and right vaginal walls at the vestibulo-vaginal fold. Testosterone, progesterone and anti-Müllerian hormone levels were within normal reference ranges. The ovarian findings were consistent with vernal transition. Karyotyping revealed mosaicism. Interventions included transecting the bands of tissue and GnRH vaccination. At follow-up examination 6 months later (autumn), the ovaries were found to be small and inactive. The owner reported improvement in behaviour. Dr. Dwyer wisely concludes that the mosaicism is an interesting finding but may be incidental.&lt;/p&gt;&lt;p&gt;Whenever equine reproduction, behaviour or sports medicine specialists gather, the conversation inevitably turns to the challenges of evaluating mare behaviour and performance cases. Dr. Dwyer's case nicely illustrates some of these challenges. It is a pleasure to have been invited to preview this report and share my comments based on experience with clinical evaluation of similar cases of mare behaviour and performance problems.&lt;/p&gt;&lt;p&gt;One of the key challenges not directly addressed in Dr. Dwyer's case report is that oestrus in mares is often poorly understood. When we ask owners and trainers to describe the specific elements of their mare's behaviour, we often find that what they describe does not align with oestrus. In our experience, the behaviours described are often more consistent with physical discomfort. For instance, vocalisations, urination, tail movements and cowering typical of guarding behaviour are commonly mistaken for the distinct vocalisations, tail movements, urination and leaning behaviour of oestrus. Many owners are not aware of the nature of oestrus during seasonal transition. Another reason we ask owners and trainers about the specifics of their mare's oestrus behaviour is that we often encounter the assumption that nearly any reduction in compliance with work or undesirable behaviour—such as stopping, refusing to go forward, kicking at the abdomen, sensitivity to touch or ‘girthiness’—is indicative of oestrus or ‘marish’ behaviour. We actually prefer to observe the behaviour firsthand, either in person or video recordings. Our evaluation includes presenting the mare to a stallion (or playing recorded stallion vocalisations and/or offering soiled bedding from a stallion if a stallion is unavailable), as well as to another mare.
