Abstract

Clinical and pathological observations were made on a case of pyometra accompanied by a large encapsulated abscess in the perimetrium in a 3-year-old primiparous Holstein cow (body weight: 549kg). With no signs of estrus since calving (on August 19, 2003), rectal palpation was conducted in September 2004, and an indurated softball-sized mass was detected on the left uterine horn. A conspicuous bulge was seen at the lower left of the abdomen when the cow was examined on February 28, 2005, and rectal palpation showed that the uterus had swollen further. Blood biochemistry and bacterial tests and ultrasonography showed a poor prognosis because of the pyometra with chronic inflammation. Autopsy, performed the following day, revealed purulent inflammation of the endometrium in addition to a giant (100×70×70cm) encapsulated abscess in the perimetrium and a severely atrophied rumen. The encapsulated abscess contained a large amount of creamy to muddy pus and blood clots. Both ovaries had no functional or regressing corpus luteum, and had become atrophied. This was considered to be a case where an abscess that developed in the perimetrium became large, in the process of which causing atrophy of the ovaries and anestrus, and this encapsulated abscess, which eventually grew to a size that occu-pied most of the abdominal cavity, caused systemic symptoms such as total anorexia.
