Plain-English summary
An 11-year-old female German Shepherd was taken to the vet because her belly was getting bigger, she had occasional bloody discharge from her vulva, and she was becoming very tired. Tests using ultrasound and X-rays showed unusual growths near her bladder. During surgery, the vet found masses on both ovaries and removed them, which was confirmed to be ovarian cystadenocarcinoma (a type of cancer). Four months after the surgery, the dog was doing well and showed no signs of the cancer spreading.
Abstract
An 11-year-old female German Shepherd dog was presented for investigation of progressive enlargement of the abdomen, periodic bloody discharge from the vulva and rapid exhaustion. Transabdominal ultrasonography and lateral abdominal radiography demonstrated an echogenic formation with anechogenic cavities located cranial to the urinary bladder and a homogeneous shadow with an elliptical shape was located caudal to the rib arc. Both showed indistinct borders. Exploratory laparotomy identified bilateral ovarian masses and ovariohysterectomy was performed. Histopathology confirmed ovarian cystadenocarcinoma. The dog remained clinically normal without evidence of metastatic disease 4 months after surgery. Papillary cystadenocarcinoma in the bitch could affect both ovaries and manifests with a rapid growth rate and clinical signs such as rapid exhaustion, abdominal enlargement and vulval discharge. Ovariohysterectomy is the treatment option.
