Magnetic resonance imaging and laparoscopic management of an ovarian remnant in a bitch.

Ovarian remnant tissue was diagnosed in a 6-year-old female Pointer presented with a history of periodic signs of oestrus after ovariohysterectomy. The diagnosis was based on clinical gynaecological examination, vaginoscopy, vaginal cytology, analysis of serum progesterone concentration, and magnetic resonance imaging. The ovarian remnant tissue was approached in a minimally invasive manner via laparoscopy and resected with a vessel-sealing system. The oestrus signs disappeared within 14 days after laparoscopy.
