title: [Pyometra and persistent hymen in an alpaca].
abstract: A 3-year-old female alpaca was referred to the hospital because of tenesmus. Clinical examination revealed a habitual vaginal prolapse with tenesmus during urination and defecation. On vaginoscopic examination a persistent hymen was detected. Ultrasonography of the caudal abdomen showed an echogenic fluid-filled uterus. A diagnostic laparotomy led to diagnosis of pyometra. Following ovariohysterectomy, the recovery was uneventful. One and a half years later the alpaca was again admitted to the hospital because of colic. Based on the findings, a tentative prognosis was provided and the alpaca was euthanized at the request of the owner. At necropsy, a haemorrhagic infarction of a jejunal loop was found due to incarceration in a fibrous adhesion between the vaginal stump and small intestine.
