RESUMO

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 Cantrells, 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 diseases

Defeitos congênitos, deformidades ou anormalidades são termos usados para descrever defeitos no desenvolvimento presentes ao nascimento, a maioria dos quais é de ocorrência rara em cadelas. Relatase 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 defeitos congênitos raros como hérnia de Morgagni (HM) e aplasia segmentar do corno uterino direito com fixação do mesmo no músculo transverso do abdome. Em associação à HM, foi observada a presença de dextrocardia e de um defeito da parede abdominal supraumbilical achados característicos da forma incompleta da pentalogia de Cantrell, síndrome até o momento só descrita em humanos. Em associação à aplasia segmentar do corno uterino foi observada a presença ipsilateral de hipoplasia renal e de agenesia de ureter. O diagnóstico destas anormalidades foi baseado nos achados macroscópicos 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.
