An aged gray stallion was examined because of fullminating posterior paresis, bladder paralysis, and perineal anesthesia. Lower motor neuron dysfunction was detected at the lumbosacral level of the spinal cord, and cerebrospinal fluid was yellow. After brief supportive treatment, the horse died. Necropsy revealed a single epidural melanoma at L5-6. The absence of cutaneous melanotic growth, absence of organ involvement, and extensive vertebral remodeling indicated the neoplasm to have been primary and to have been present for an extended period. Neurologic dysfunction was acute and progressive, as a result of spinal cord compression by the neoplasm.
一匹老年灰色种马因突发后肢轻瘫、膀胱麻痹和会阴感觉缺失而接受检查。在脊髓腰荐部水平检测到下运动神经元功能障碍，脑脊液呈黄色。经过短暂的支持治疗后，这匹马死亡。尸检发现L5 - 6处有一个单一的硬膜外黑色素瘤。皮肤无黑色素性肿物生长、无器官受累以及广泛的椎体重塑表明该肿瘤为原发性且已存在较长时间。由于肿瘤对脊髓的压迫，神经功能障碍呈急性且进行性发展。
