The clinical signs, magnetic resonance imaging (MRI) findings, treatment and follow-up in seven dogs with hydrated nucleus pulposus extrusion (HNPE) are reported. All dogs had tetraparesis or tetraplegia. T2-weighted MRI revealed extradural hyperintense homogeneous material compressing the cervical spinal cord. After conservative treatment (five dogs) or surgical decompression (two dogs), all dogs returned to ambulatory function within 1 month. Follow-up MRI in conservatively treated dogs revealed complete disappearance of the extruded material. Histopathological examination of surgical specimens confirmed that the retrieved material was extruded nucleus pulposus with evidence of early degeneration.
报告了7只患有水合髓核突出（HNPE）犬的临床体征、磁共振成像（MRI）结果、治疗及随访情况。所有犬均出现四肢轻瘫或四肢瘫痪。T2加权MRI显示硬膜外高强度均匀物质压迫颈脊髓。经过保守治疗（5只犬）或手术减压（2只犬）后，所有犬在1个月内恢复了行走功能。保守治疗犬的随访MRI显示突出物质完全消失。手术标本的组织病理学检查证实，取出的物质为突出的髓核并有早期退变迹象。
