Abstract
Routine ultrasonographic evaluation of the genital organs of a 3-year-old terrier bitch revealed a mass at the level of the left ovary. The mass was located next to the caudal pole of the left kidney and ventrocaudal to the left ovary. Ultrasonographically, the uterus was not enlarged and had no luminal contents. Exploratory laparotomy revealed a mass attached to the left ovarian bursa with a small and thin pedicle. The mass had smooth margins, was whitish in color, and was lobulated on cut surface. The histopathological diagnosis of the mass was leiomyoma associated with the mesosalpinx.
