Summary:Birth defects, deformities or abnormalities are terms used to describe developmental defects present at birth, most of which are rare in bitches. We report the case of a six-month old mongrel bitch corpse, which, when subjected to an anatomotopographic study revealed the presence of rare birth defects as Morgagni hernia and segmental aplasia of the right uterine horn with its attachment to the transverses muscle of abdominis. In association with HM, we observed the presence of dextrocardia and a defect of the abdominal wall supraumbilical characteristic of incompletely Pentalogy of Cantrell’s, syndrome so far described only in humans. In association with segmental aplasia of the uterine horn, we observed the ipsilateral presence of the renal hypoplasia and ureteral agenesis. The diagnosis of those abnormalities was based on anatomical findings and confirmed histologically. Despite the rarity and complexity of the abnormalities first described in bitches, the literature suggested that the prognosis may be favorable to the life of the animal. However, early diagnosis is essential to avoid the potential complications of those diseasesDefeitos congênitos, deformidades ou anormalidades são termos usados para descrever defeitos no desenvolvimento presentes ao nascimento. A maioria destes, como a aplasia segmentar uterina, é de ocorrência rara em cadelas. Relata-se o caso de um cadáver de cadela, sem raça definida, de seis meses de idade, que ao ser submetido ao estudo anatomotopográfico revelou a presença de aplasia segmentar uterina (ASU) associada à hérnia de Morgagni (HM), agenesia ureteral (AU) e hipoplasia renal direita (HR). Além destas anormalidades, foi observada a presença de dextrocardia e de um defeito da parede abdominal supraumbilical, que caracterizam a forma incompleta da pentalogia de Cantrell, só descrita em humanos. O diagnóstico destas anormalidades foi baseado nos achados anatômicos e confirmado histologicamente. A despeito da raridade e complexidade das anormalidades descritas pela primeira vez em cadelas, a literatura sugeriu que o prognóstico pode ser favorável à vida do animal. Contudo, o diagnóstico precoce é essencial para se evitar as possíveis complicações destas patologias.
