Stump pyometra and ovarian remnant in a 6 year old FS Rottweiler dog

History

A 6-year-old FS Rottweiler adopted three years ago from a shelter at which she was spayed, was presented for a history of two heat cycles, a negative LH test two years prior and recent bloody and mucoid discharge from the vulva. Abnormalities on physical examination were a grade II/VI heart murmur and a bloody, mucoid vulvar discharge.

Comments

At the suture removal appointment, the patient was found to be doing well with a healed incision.

Clinical Differential Diagnosis

Retained ovarian tissue, vaginitis, stump pyometra, vaginal tumor.

DX

Right ovarian remnant. Stump pyometra.

Sampling

Full-thickness surgical biopsy from the right ovary revealed multiple corpora lutea, within normal histologic limits. A biopsy from the uterine stump revealed chronic metritis.

Sonographic Differential Diagnosis

Right ovarian remnant. Stump pyometra.

Image Interpretation

A 3.0 cm wide, fluid-filled uterine remnant was noted in this patient with a thickened wall. This is consistent with stump pyometra. This remnant continued into the level of the apex of the urinary bladder. Right ovarian remnant was also present at 2 x 2.25 cm and in normal position for an ovary.

Outcome

A repeat ovariohysterectomy, with antibiotic therapy prior to surgery and three weeks post-operatively, was recommended. The patient was treated with Clavamox prior to undergoing a repeat ovariohysterectomy. The patient recovered well, but had some minimal serosanguinous oozing from the incision two days post-operative. The patient was treated with Yunnan Paio, and the owner was instructed to apply cold compresses every two hours.
