ABSTRACT
Background: The myxomatosis degeneration is a degenerative cardiac valve disease, with a higher incidence in maleand senile canids. The diagnosis is made by a doppler echocardiography exam. Although there are few reports on the occurrence of cardiopathies in wild dogs (Cerdocyon thous), some studies on their cardiological parameters can be found.Considering this, and knowing that the cardiopathies in wild canids are common post mortem findings, the objective of thisstudy is to describe the echocardiography diagnosis of a case of myxomatous degeneration of the atrioventricular valvesin 1 wild dog (Cerdocyon thous) living in captivity.Case: It was treated at the Diagnostic Imaging Department of the Veterinary Hospital of the Federal University of Mato Grosso(HOVET-UFMT), 1 wild dog (C. thous), male, living in captivity with approximately 10-year-old, directed by the Center ofMedicine and Research in Wild Animals of Cuiabá, to perform echocardiography exam. The patient was submitted to anesthesiafor proper examination, which was used Esaote® machine model MyLabFive VET with sector scan transducer (4.0 -7.5 MHz).The longitudinal, transverse and apical scan planes were obtained through left and right parasternal windows. The evaluation ofM mode exposed ejection fraction and shortening increased, of 81% and 47%, respectively, however it showed no increase insystolic and diastolic values of left ventricle, nor in right cavities on subjective evaluation. The relation between the left atrium(LA) and the aorta (Ao) remained normal, at 1.2 mm, with dimensions of 13.4 mm from the AO and 16.3 mm from LA, compatible with species parameters or domestic canines. The atrioventricular valves showed thickening and irregularities in their cusps,with great intensity in the left atrioventricular valve (LAV). The Doppler mode analysis revealed a turbulent systolic flow into the...

Background: Renal dysplasia is a congenital disorder that occurs during differentiation of the renal parenchyma or as aconsequence of a functional and/or structural obstruction of the lower urinary tract. In wild animals, this pathology has beenreported in cynomolgus monkeys (Macaca fascicularis), golden hamsters (Mesocricetus auratus) and African elephants(Loxodanta africana). However, there are no reports of the disease in the giant anteater (Myrmecophaga tridactyla). Thus,this paper describes a case of renal dysplasia in a free-living giant anteater cub, which was sent to the wild animal clinicof the Federal University of Mato Grosso (UFMT) in Cuiabá, MT, Brazil.Case: The rescued animal had a good body condition score and clinical parameters within the normal range for the species.After a routine clinical evaluation, the anteater cub was subjected to radiography and ultrasound tests. Blood tests, serumtests for hepatic and renal profiles, urinalysis, urinary protein creatinine ratio, and chest X-rays did not reveal significantchanges. However, the abdominal ultrasound examination revealed a volumetric loss of about 1.17 cm in length in theleft kidney, and a renal length to aortic artery diameter ratio of approximately 2.8. This kidney showed irregular contours,loss of corticomedullary demarcation, with preserved echogenicity and cortical echotexture. The right kidney showedthe standard size of the species, with a length of approximately 3.08 cm. In view of the suspicion of renal dysplasia, acontrast-enhanced CT scan was performed in order to assess the dynamics of uptake and excretion of the contrast mediumin the affected kidney and in the ipsilateral collecting system. An examination of the tomographic images indicated thatthe volume of the left kidney was reduced, isodense in relation to the right kidney, with discrete and homogeneous uptakein all phases after administration of the contrast medium, no occurrence of nephrogram...
