Popis: portuguesEste relato descreve os aspectos epidemiologicos, clinicos e anatomopatologicos de um caso de mielopatia isquemica por embolismo fibrocartilaginoso (FCE) em um equino, macho castrado, sem raca definida, com 10 anos de idade. Clinicamente, o equino apresentou paralisia aguda dos membros pelvicos com evolucao de aproximadamente 24 horas. Na necropsia nao foram observadas alteracoes. Apos serem realizados varios cortes transversais na medula espinhal, observou-se area focalmente extensa de malacia entre o segmento T10 ate L4. Histologicamente haviam areas focalmente extensas de necrose de liquefacao envolvendo a substância cinzenta e a substância branca adjacente. Multiplos vasos sanguineos da periferia das areas de necrose estavam ocluidos por embolos fibrocartilaginosos, que reagiram fortemente pela tecnica de azul alciano. Os sinais clinicos, as lesoes macroscopicas e os achados histologicos observados neste caso, sao identicos aos descritos na literatura para FCE em equinos e nas demais especies.

Clinically, the horse presented acute hind limbs paralysis, with a clinical course of approximately 24 hours. At necropsy, no gross lesions were observed. Cross-sections of the spinal cord revealed focally extensive areas of malacia from the T10 to L4 segments. Focally extensive areas of liquefactive necrosis involving the gray matter and adjacent white matter were observed on histologic sections. The lumen of multiple blood vessels in the periphery of the necrotic areas was occluded by fibrocartilaginous emboli that strongly stained with alcian blue. Clinical signs, gross necropsy, and histological findings observed in this case were identical to those described in the literature for ischemic myelopathy caused by FCE in the horse and other species.
