Abstract: | A 4.5-year-old female domestic longhair cat with a history of intermittent abdominal distention following estrus and infertility was admitted for routine vaccinations. Radiographs revealed 2 large blunt-ended tubular structures overlapping each other in the abdomen. Segmental aplasia of the right uterine horn was diagnosed following exploratory laparotomy and ovariohysterectomy. |
