Background: Uterine twisting in bitches is an uncommon disease in which the difficulty of diagnosis is due to non specific clinical signs. This condition is more commonly observed in pluriparous females and is usually associated with a pregnant uterus close to birth, or associated with hemometra, pyometra and neoplasms in non-pregnant bitches. This study reports a case of an 11-year-old Poodle bitch with a rare case of uterine twisting in a non-pregnant womb. Case: A 11-year-old Poodle dog, weighing 3.2 kg, was admitted at the institution with a history of anorexia, oligodipsia and apathy during one day. There was no information on the last phase of estrus or previous pregnancies. The patient arrived at the emergency room of the veterinary hospital with cardiorespiratory arrest and was resuscitated with mechanical ventilation, cardiac massage and administration of adrenaline (0.1 mg/kg IV, 1 mg/ml concentration), tramadol hydrochloride (2mg/kg via IV) and oxygen therapy. Clinical examination revealed a distended and tense abdomen with a palpable mass inthe mesogastric region. Ultrasound examination showed a heterogeneous structure (> 10cm. in diameter), with cavitary areas filled with heterogeneous anechoic content and septations, located between the liver and urinary bladder. It was notpossible to identify in which organ or structure the mass originated, and the possibility of gestation and fetal death was discarded. The female died six hours after admission. The patient was submitted to necropsy and histopathological analysis revealed a dark red and enlarged segment of the uterine horn with a 360º twist, occupying most of the abdominal cavity.The left uterine horn was about 10 cm in diameter and firm, and cystic areas were observed on a reddish-black surface containing a large amount of bloody fluid. The right uterine horn was normal in appearance, but with a small amount of fluid...(AU)
