Plain-English summary

An 18-month-old female German shepherd was brought in because she was bleeding heavily from her vulva. Tests showed she had a lot of blood loss, and an ultrasound revealed that her uterus was swollen and filled with fluid and suspected blood clots. During surgery, the vet found her uterus was enlarged and filled with blood and yellow fluid, which was likely an infection. A tissue examination confirmed she had a serious condition called cystic endometrial hyperplasia and pyometra (a severe infection of the uterus). The treatment involved surgery to address these issues.

Abstract

An 18-month-old, intact female German shepherd dog was presented for evaluation of severe, frank hemorrhage from the vulva. A complete blood count, serum biochemical analysis, and urinalysis supported acute hemorrhage. Abdominal radiographs were unremarkable. Abdominal ultrasound demonstrated that the uterine body and cranial vaginal lumen were fluid-filled and contained hyperechoic, polypoid masses that were suspected to be blood clots. Exploratory laparotomy revealed a mildly enlarged uterus with a diffuse, cystic endometrium; significant amounts of blood and blood clots within the lumen; and several focal accumulations of yellow fluid presumed to be a purulent exudate. Histopathology confirmed severe, cystic, endometrial hyperplasia and pyometra complex.
