This report describes the clinical presentation, diagnosis and treatment of a queen with open pyometra. Lethargy, anorexia and previous treatment failure were the main reasons resulting in referral for diagnostic evaluation. The history, haematological and biochemical profiles and abdominal radiographs revealed open pyometra. Following ovariohysterectomy and antibiotic therapy there was total resolution of clinical signs. Histopathology of the uterus showed severe calcification. The unique part of this report was the rare appearance of multiple opacities in the radiographs. To the authors' knowledge, this is the first report of radiographic opacities in a domestic short-haired queen with open pyometra.Keywords: queen; pyometra; radiology; uterus; calcification Pyometra is the most frequent and important endometrial disorder in intact, sexually mature queens and is characterised by uterine infection by ascending vaginal bacteria as a consequence of progesterone stimulation of the endometrium. It may involve diffuse or segmental enlargement of the uterus. Histological lesions range from simple cystic endometrial hyperplasia to endometrial atrophy (Nak et al. 2009).Pyometra is classified as open-cervix or closedcervix based on cervical patency for drainage of purulent uterine fluid. Although medical management may be attempted, surgical intervention to prevent uterine rupture and septicaemia is the treatment of choice for any open-cervix pyometra where the bitch is systemically ill, or any case of closed-cervix pyometra (Adamovich-Rippe et al. 2013).In this paper, we describe an unusual feature of open pyometra in a queen, and its radiographic and histopathological change. Case descriptionA 4.3 kg, approximately six-year-old sexually intact female Domestic short-haired cat was presented to the Small Animal Hospital, University of Tehran, Tehran, Iran because of a history of anorexia and lethargy. The cat had lived indoors for approximately five years and had not been bred during this period of time. Two weeks prior to presentation she had the same clinical signs (lethargy and anorexia) and the owner referred her to a private pet clinic. The veterinarian prescribed antibiotics and intravenous lactated Ringer's solution, which initially resulted in improvement before a subsequent return of the clinical symptoms.On initial physical examination, the cat was mildly dehydrated and lethargic. Rectal temperature was normal (38.1 °C) and no abnormalities in mucous membrane colour were noted. Heart and respiratory sounds and rates were normal. Vaginal discharge was not observed and abdominal palpation revealed no abnormal organs. Polyuria and polydipsia were noted by the owner.Diagnostic procedures included a complete blood count (CBC), serum biochemical profile and abdominal radiographs. The CBC showed mild nonregenerative normocytic normochromic anaemia, leucocytosis with neutrophilia and the presence of immature WBCs in a peripheral blood sample.
The aim of this descriptive study was to monitor the changes in uterine arteries during pregnancy, postpartum period and pyometra in bitches using angiography. Fifteen uteri of mixed breed bitches on days 24, 30, 33, 40, 43, 47, 50 and 56 of pregnancy and weeks 1, 2, 3, 4 and 7–8 of postpartum and two CEH/pyometra bitches were examined after ovariohysterectomy. The results showed that with the onset of normal pregnancy and in about 30 ± 1 days of gestation, anastomoses begin to form between the left and right middle uterine arteries, developing during the next days and continuing until 4 weeks postpartum. On 4th week after parturition, when physiologic changes occur and the uterus returns to non‐pregnant conditions, these anastomoses begin to degenerate, and they completely disappear approximately on the 7th–8th week after parturition. Similarly, in CEH/pyometra bitches, anastomoses were formed between left and right median uterine arteries. These findings can be considered as a part of the physiological changes of the uterus and its vessels during pregnancy and postpartum periods and could affect the results and interpretation of relevant findings.
A 2-month-old female German shepherd dog was presented with a history of unilateral ocular discharge and corneal opacity to the Veterinary Teaching Hospital of Shiraz University. On ophthalmic examination, the right eye was slightly buphthalmic with corneal edema, vascularization, and fibrosis, whereas, the left one had its normal size and shape. However, a deep corneal ulcer and fibrosis was also detected. Complete ophthalmoscopic examination of the right globe was not possible because of the edema and fibrosis. As a result, ultrasonography was performed. B-mode ultrasonography of the right eye revealed a subcapsular cataract. Behind and attached to the lens, a triangular-shaped echogenicity was seen which continued as a tubular hyperechoic structure to the optic disk. In contrast, the left eye was normal ultrasonographically. On the basis of the ultrasonographic findings for the right eye, the clinical diagnosis of unilateral persistent hyperplastic tunica vasculosa lentis/ persistent hyperplastic primary vitreous (PHTVL/PHPV) was made.
