Pyometra in a 13-year-old neutered queen

Abstract

A 13-year-old female domestic shorthair cat was examined because of weight loss over 4 months. The history included being neutered when a kitten and no signs of estrus recognized by the owner since this surgery. A mid-abdominal mass was palpated. Ultrasonographic abdominal evaluation revealed a tubular fluid-filled mass. The cat underwent surgery to remove the mass, which was one horn of the uterus. The patient made a full recovery.
