Unilateral uterine torsion in two non‐gravid bitches : imaging and histological features

A 4-year-old nulliparous Labrador Retriever bitch and a 7-year-old nulliparous crossbreed bitch were referred for weakness and vomiting. Ultrasonographic examination revealed in both cases a large abdominal mass-lesion with corpuscular fluid content; computed tomography examination revealed in both cases the uterine origin of the lesions, with findings consistent with torsion. Surgery confirmed the uterine torsion upon the ovarian pedicle in both cases, and at histological examination both presented a uterine polyp associated with haemorrhage and necrosis of the uterine wall. Both patients were released in good clinical conditions.
