A 4-year-old Suffolk ewe in the last trimester of gestation was referred to Veterinary Teaching Hospital with history of an acute, progressive, bilateral abdominal distention. After 10 days of hospitalization, the animal underwent a cesarean section in the paramammary region that revealed a grossly distended, thin-walled, fluid-filled uterus with 18 liters of allantoic fluid and 2 lambs. Two days after surgery, the ewe was alert, able to stand and had normal appetite. Abdominal distention did not recur after surgery and neither retention of fetal membranes nor septic metritis signs were observed. Ten days after surgery the animal was discharged to the farm. Rebreeding was discouraged in this case. KEY WORDS: Hydrallantois. Ewe.
Uma ovelha da raça Suffolk, 4 anos de idade, no terceiro trimestre de gestação foi encaminhada ao Hospital Veterinário com história primária de distensão abdominal bilateral aguda e progressiva. Após 10 dias de internação, o animal foi submetido a uma cesariana na região paramamária que revelou útero distendido com paredes finas e preenchido com 18 litros de líquido alantóico e presença de 2 cordeiros. Dois dias após a cirurgia, a ovelha estava alerta, era capaz de se levantar e tinha apetite normal. A distensão abdominal não retornou após a cirurgia nem retenção de placenta ou sinais de metrite foram observados. Dez dias após a cirurgia o animal retornou para a fazenda. Nova cobertura foi desencorajada neste caso.PALAVRAS-CHAVE: Hidroalantóide. Ovelha

The purpose of this research was to make the comparative histological evaluation of uterus and ovaries of nulliparous and multiparous cats and others submitted to hormonal treatment with progesterone. Ten samples of right and left uterine horns and ovaries for each group had been used for this end. The material collected soon after surgery, was processed routinely, stained with haematoxylin and eosin and examined to the light microscope. The uterus of nulliparous cats presented thin endometrium with discrete longitudinal folds coated by cubical simple epithelium. The glands were discrete, in small number and reduced diameter, formed for low cubical or cylindrical epithelium. However in multiparous cats, the endometrium was plaited, irregular and thick, coated for cylindrical simple epithelium with vacuolated cells, some cases, with dilated glands formed for flattened epithelium, the same occurring for the ones treated, that beyond endometrial reduction and branched, presented innumerable high projections and richly ramified coated by cubical and cylindrical simple epithelium with vacuolated cells. The glands of reduced diameter were formed for cubical or cylindrical simple epithelium and the dilated glands show secretion and cystic appearance. The myometrial layers in nulliparous cats were regular with great amount of blood vessels of great diameter between the layers, in contr
