Abstract：
An 8-year-old rabbit presented with a 5-day history of acute difficulty in walking. Neurological examination revealed tetraparesis, proprioceptive deficits in both pelvic limbs and the right thoracic limb, decreased withdrawal reflex on the right thoracic limb and hyperreflexia in the pelvic limbs. A cervico-thoracic (C6-T2) localization was suspected. Computer tomography (CT) and magnetic resonance imaging (MRI) scans were performed, revealing a right dorsolateral extradural lesion at the C6-C7 intervertebral disc space. Additionally, meningeal and paravertebral contrast enhancement was observed on MRI, while periosteal reaction was evident at the right C6-C7 facet joint on CT. The findings were primarily consistent with spinal cord compression due to the presence of extruded disc material. Following conservative treatment failure, a right-sided C6-C7 hemilaminectomy was performed to remove the compression and sample the extradural material. Histological examination confirmed the presence of degenerated and partially mineralized disc material mixed with granulation tissue. This is the first reported case of cervical disc extrusion in a rabbit, confirmed by histological examination.
摘要：
一只8岁的兔子，有5天的行走困难史。神经系统检查显示有四瘫,骨盆肢体和右胸肢的本体感觉缺陷，右侧胸肢的退缩反射减少，骨盆四肢的反射亢进减少。怀疑颈胸（C6-T2）定位。进行了计算机断层扫描（CT）和磁共振成像（MRI）扫描，在C6-C7椎间盘间隙显示右背外侧硬膜外病变。此外,在MRI上观察到脑膜和椎旁对比增强，而CT显示右侧C6-C7小关节处骨膜反应明显。由于存在挤压的椎间盘材料，该发现主要与脊髓压迫一致。保守治疗失败后，我们进行了右侧C6-C7半椎板切除术,以移除压迫物并取样硬膜外材料.组织学检查证实存在与肉芽组织混合的变性和部分矿化的椎间盘材料。这是首例报道的兔颈椎间盘挤压症，经组织学检查证实。
