Case Study

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

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.

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.

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.

DX

Right ovarian remnant. Stump pyometra.

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.

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.

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.
