UNILATERAL FIBROSIS OF UTERINE HORN ASSOCIATED WITH UNILATERAL PYOMETRA IN A SPITZ BITCH :case report

Unilateral pyometra in female dogs can arise from several uterine irregularities. Aplasia of the uterine horn has been linked to both pyometra and mucometra, likely due to cystic endometrial hyperplasia. The onset of unilateral pyometra is frequently connected to compromised uterine drainage, which may result from issues like uterine torsion or stenosis. Inflammatory endometrial polyps may cause unilateral uterine torsion, thereby raising the likelihood of developing pyometra. A five-year-old, non-pregnant Spitz was presented at the clinic exhibiting signs of abdominal discomfort, excessive licking of the vulva, loss of appetite, and lethargy. The dog's medical history revealed she had been in heat about five weeks before the visit. Upon examination at the clinic, her vital signs were recorded as follows: a body temperature of ۳۹.۳°C, a heart rate of ۱۷۰ beats per minute, and a respiratory rate of ۳۳ breaths per minute. The physical assessment showed an inflamed vulva without any discharge. Chest x-rays indicated a heart of normal size and slight broncho-interstitial changes in the lungs. Ultrasound imaging revealed that the left uterine horn was enlarged and filled with fluid, while both ovaries appeared normal and had anechoic areas. Blood analysis indicated a marked elevation in white blood cell count, confirming the diagnosis of pyometra. After administering fluid therapy and stabilizing the dog’s condition, she underwent a laparotomy and ovariohysterectomy. The surgical findings uncovered unilateral fibrosis in the left uterine horn, which was identified as the root cause of the unilateral pyometra. This uncommon condition is characterized by a small, yet fully formed fibrotic lesion located at the junction of the uterine horn and body, often accompanied by systemic clinical symptoms in female dogs.
