Atypical presentation of ovarian remnant syndrome in a dog.

Abstract

A 2 yr old spayed female dog presented for evaluation of abdominal pain, decreased appetite, dysuria, and frantic licking of her vulva. A midventral, soft, fluctuant mass was detected on abdominal palpation. Diagnostic testing and exploratory celiotomy revealed remnant ovarian tissue and a cystic uterine remnant. The ovary and cystic uterine remnant were removed and submitted for histopathological evaluation. Ovarian remnant syndrome (ORS) is an infrequently encountered condition of dogs. This dog had none of the classic signs of estrus associated with ORS but instead presented for sharp, intermittent, abdominal pain that is similar to women with ORS.
