Plain-English summary
A 13-year-old Icelandic mare that had never been bred was experiencing ongoing vaginal discharge, which led to a diagnosis of a rare condition called pyometra (an infection in the uterus). Tests showed that she had unusual spherical masses inside her uterus, which were later confirmed to be pus-filled lumps. These lumps were successfully removed using a special procedure, and she received antibiotics for ten days. However, after treatment, the mare developed pyometra again because her cervix was blocked, but this was resolved by placing a stent to keep the cervix open and prevent fluid buildup. Overall, the treatment worked to remove the masses, but the underlying issue with the cervix needed additional intervention.
Abstract
Pyometra is an uncommon condition in mares associated with various symptoms. Here, we report a case of a 13-year-old Icelandic barren maiden mare with recurrent vaginal discharge. Ultrasonographically, the mare displayed intrauterine spherical masses of inhomogenous texture, which were identified as purulent concrements in hysteroscopy. The purulent concrements were successfully removed via uterine lavage after endoscope-assisted comminution. Microbiologic examination of the concrements revealed growth of Streptococcus equi subspecies zooepidemicus, Actinobacillus species, Pseudomonas aeruginosa, Staphylococcus intermedius, Pseudomonas fulva, Citrobacter freundii, and Chryseobacterium species. Systemic antibiotic treatment with trimethoprim-sulfadiazine and additional uterine lavages were performed for 10 days. A follow-up examination revealed absence of intrauterine masses but reoccurrence of pyometra due to an impatent cervical canal. The pyometra condition was resolved by insertion of a cervical stent for prevention of intrauterine fluid accumulation. In conclusion, uterine masses, which may severely impact fertility, are best diagnosed by hysteroscopy. Intrauterine purulent concrements should be considered as an atypical form of equine pyometra.
