Summary

A 5-year-old female intact Mastiff dog was presented with a history of vaginal discharge for 1 day. Physical examination revealed a sanguineo- purulent vaginal discharge and systemic inflammatory response syndrome. Abdominal radiographs showed several dilated and gasfilled tubular loops. The differential diagnoses included emphysematous pyometra or small intestinal mechanical ileus. Surgical exploration of the abdomen demonstrated a severely dilated and gas-filled uterus, and emphysematous pyometra was confirmed. The patient’s clinical signs resolved after ovariohysterectomy. Histopathology revealed mild endometrial cystic hyperplasia with infiltration of inflammatory cells in the superficial endometrial epithelia. Enterococcus avium, an α-hemolytic gram-positive coccus, was isolated from the uterus. This paper highlights the radiographic features of emphysematous pyometra and a pathogen that has never been reported to be associated with canine pyometra previously.

Zusammenfassung

Eine 5-jährige weiblich-intakte Mastiff-Hündin wurde mit seit einem Tag bestehenden Vaginalausfluss vorgestellt. Die Allgemeinuntersu - chung ergab blutig-eitrigen Vaginalausfluss und ein systemisches inflammatorisches Response-Syndrom. Auf Röntgenaufnahmen des Abdomens waren mehrere dilatierte, gasgefüllte tubuläre Schleifen zu erkennen. Differenzialdiagnostisch wurden eine emphysematöse Pyometra oder ein mechanischer Ileus der Dünndärme erwogen. Bei der Laparotomie konnte aufgrund eines stark dilatierten, gasgefüllten Uterus eine emphysematöse Pyometra bestätigt werden. Klinische Symptome waren nach der Ovariohysterektomie nicht mehr vorhanden. Histopathologisch wurde eine geringgradige zystische Hyperplasie des Endometriums mit Infiltration entzündlicher Zellen im superfiziellen endometrialen Epithel nachgewiesen. Aus dem Uterus ließ sich Enterococcus avium, ein grampositives, α-hämolytisches Kokkenbakterium, isolieren. Der Fallbericht stellt die röntgenologischen Merkmale der emphysematösen Pyometra dar und beschreibt die Infektion mit einem Krankheitserreger, der im Zusammenhang mit der Pyometra des Hundes bisher nicht beschrieben wurde.
