Intervertebral disk extrusions into the spinal cord are rarely reported in veterinary medicine, and only necropsy findings are described in previous reports. It is hypothesized that a disk lesion results in forceful injection of disk material into the spinal cord. In the 3-year-old Miniature Doberman Pinscher of our report, acute clinical signs and results of magnetic resonance imaging were consistent with this disease and helped determine the extent and character of the lesions. Alteration in the appearance of the nucleus pulposus was important in determining that intervertebral disk disease may have been present in this dog. However, a definitive diagnosis of intramedullary disk extrusion can be made only via histologic examination of a biopsy specimen or at necropsy. The dog improved substantially after surgical decompression of the spinal cord, and histologic findings in a biopsy specimen of material found within the spinal cord were consistent with mature degenerate intervertebral disk material.
椎间盘突出至脊髓在兽医医学中鲜有报道，既往报告仅描述了尸检结果。据推测，椎间盘病变导致椎间盘物质强力注入脊髓。在我们报告的这只3岁迷你杜宾犬中，急性临床症状和磁共振成像结果与该病相符，有助于确定病变的范围和特征。髓核外观的改变对于确定这只犬可能存在椎间盘疾病很重要。然而，髓内椎间盘突出的明确诊断只能通过活检标本的组织学检查或尸检来做出。这只犬在脊髓手术减压后有显著改善，脊髓内材料活检标本的组织学结果与成熟退变的椎间盘物质一致。
