Hérnia diafragmática e agenesia renal unilateral em cachorro-do-mato (Cerdocyon thous) – Relato de caso.

Abstract

The crab-eating fox is a medium-sized canid found in South America, which has nocturnal and omnivorous habits, with a diverse diet, ranging from fruits to small mammals. The ocurrence of congenital malformations in wild animals is not well documented, but the causes are similar to the ones in domestic species, having their origin in organogenesis. Diaphragmatic hernia is a discontinuity of the diaphragm muscle, a condition that allows the displacement of the abdominal organs towards the interior of the thoracic cavity, which can be congenital or acquired. Congenital kidney disorders are functional and / or morphological abnormalities of the organ, which compromise renal growth and development, the agenesis is the condition characterized by the absence of one or both kidneys. The objective of this study is to report a clinical case of an animal of the species Cerdocyon thous, which shows high signs of a congenital diaphragmatic hernia and unilateral renal agenesis. After anamnesis, physical examination, laboratory tests and imaging tests, in which the patient was diagnosed with diaphragmatic hernia, ectopic kidney, renomegaly and non-visualization of the contralateral kidney, suggesting a reserved prognosis for the case after the presence of respiratory symptoms. The patient died and a necropsy was performed, which confirmed the imaging findings and diagnosed unilateral renal agenesis.
