RESUMO
Relata-se o caso de uma égua de atividade de polo, que apresentou inicialmente claudicação leve no membro posterior esquerdo, a qual evoluiu para ataxia e atrofia da musculatura glútea do lado esquerdo, com diagnóstico de trombose aortoilíaca (TAI). A paciente foi tratada com suspeita de mieloencefalite protozoária equina, devido à semelhança dos sinais clínicos com essa doença, porém o líquido cefalorraquidiano apresentou-se negativo para anticorpos anti-Sarcocystis neurona. A palpação transretal indicou uma massa na bifurcação aortoilíaca esquerda. Na avaliação ultrassonográfica, visualizou-se imagem hiperecoica aderida ao endotélio vascular, sugerindo TAI atingindo a estenose de 70 por cento da luz arterial.
ABSTRACT
The case of a mare used for polo is reported. The animal showed clinical signs of soft lameness of the hindlimb, evolving to ataxia and gluteal muscle atrophy, with aorto-iliac thrombosis (AIT). The patient was treated with the suspect of equine protozoal myeloencephalitis (EPM), due to the resemblance of clinical signs. Cerebrospinal fluid analysis was negative for antibodies against Sarcocystis neurona. The transrectal examination indicated a mass in the left aorto-iliac bifurcation. In the ultrasonographic evaluation, a hyperechoic image adhered to the vascular endothelium was observed, suggesting (AIT), occupying 70 percent of arterial lumen. The present article has the objective of pointing out the importance of the differential diagnosis between AIT and EPM in horses with ataxia in hindlimbs and muscular atrophy.
