Three dogs were presented with lumbosacral hyperesthesia. Computerized tomography scans were performed in all the cases, and magnetic resonance imaging was also performed in cases 1 and 3. There was intervertebral disc (IVD) protrusion causing nerve root compression and epidural gas accumulation in all the three cases. The gas-filled cystic structures in cases 1 and 3 were within the spinal canal; in case 2, the gas was within the disc protrusion. The IVD vacuum phenomenon is relatively common in dogs, but the formation of an epidural gas accumulation in cases of a lumbar disc protrusion is rare. The clinical significance of these epidural gas accumulations is unknown. Two of the dogs were treated surgically, improved after surgery, and showed no signs of pain in the follow-up examinations.
三只犬出现腰骶部感觉过敏。所有病例均进行了计算机断层扫描,病例1和3还进行了磁共振成像。所有三个病例均存在椎间盘突出导致神经根受压和硬膜外气体积聚。病例1和3中充满气体的囊性结构位于椎管内;病例2中,气体位于椎间盘突出部位。椎间盘真空现象在犬中相对常见,但腰椎间盘突出病例中硬膜外气体积聚的形成很少见。这些硬膜外气体积聚的临床意义尚不清楚。其中两只犬接受了手术治疗,术后病情改善,在随访检查中未出现疼痛迹象。
