A young stray entire female domestic shorthair cat was presented with symmetrical forelimb extensor rigidity, neck hyperextension and hindlimb paraplegia, characteristic of Schiff-Sherrington phenomenon (SSP), within 30 min of a motor vehicle accident. Radiographic and post-mortem studies disclosed complete transection of the spinal cord from traumatic dorsocranial luxation of the second lumbar vertebra, displacement of the sacrum from the ilium, seventh lumbar and first caudal vertebrae and multiple pelvic fractures. Other causes of forelimb extensor rigidity and neck hyperextension such as decerebrate and decerebellate rigidity were excluded by a lack of neurological signs consistent with these entities and unremarkable findings on post-mortem examination of the cranial cavity and brain and histological examination of the cerebrum, brainstem and cerebellum. To the best of the author's knowledge, this is the first report of SSP in the cat outside the experimental arena of decerebrate or non-decerebrate preparations following post-brachial spinal cord transection/cold block.
一只年轻的流浪全雌性家短毛猫，在遭受机动车事故后 30 分钟内出现对称性前肢伸肌僵硬、颈部过度伸展和后肢截瘫，具有 Schiff-Sherrington 现象（SSP）的特征。放射学和尸检研究显示，第二腰椎的创伤性颅背侧脱位导致脊髓完全横断，骶骨从髂骨、第七腰椎和第一尾椎脱位，并伴有多处骨盆骨折。通过缺乏与这些病变一致的神经体征，以及对颅腔和大脑的尸检和大脑、脑干和小脑的组织学检查未发现明显异常，可以排除去大脑和去小脑僵硬等导致前肢伸肌僵硬和颈部过度伸展的其他原因。据作者所知，这是在去大脑或非去大脑制剂实验领域之外，臂丛脊髓横断/冷阻断后首次在猫中报告 SSP。
