Abstract：
A 3.5-year-old male intact Staffordshire terrier crossbreed dog was presented with a one-week history of progressive paraparesis with fecal and urinary incontinence. Neurological examination was consistent with a T3-L3 myelopathy. A magnetic resonance imaging study revealed the presence of a well-circumscribed hemorrhagic space-occupying lesion at the level of T12, suspected to be a vascular malformation, such as cavernoma or arteriovenous fistula, primary hematoma or hamartoma; less likely considerations included hemorrhagic inflammation or hemorrhagic primary or secondary neoplasia. A dorsal laminectomy, durotomy, and midline dorsal myelotomy were performed with a surgical microscope, and the vascular lesion was identified and removed. Histological examination of surgical samples yielded fibrin, hemorrhage, hematoidin pigment, and some neural tissue. Although a lining wall was visualized during surgery consistent with a vascular malformation, there was no histological confirmation of such a structure, hampering definitive classification of the lesion. There was no gross or histopathological evidence that would support a diagnosis of a hamartoma or benign neoplasia. The dog was paraplegic with intact nociception the day following surgery. Ambulation was recovered within 2 weeks. Progressive and complete recovery of neurological function was seen over the next 12 weeks. No recurrence of neurological dysfunction was seen over a 12-month follow-up period. Surgical treatment should be considered in dogs with spinal intramedullary vascular lesions which can have a successful long-term outcome.
摘要：
一只3.5岁的雄性完整的斯塔福德郡猎犬杂种犬有一周的进行性轻瘫伴粪便和尿失禁病史。神经系统检查与T3-L3脊髓病一致。磁共振成像研究显示，在T12水平存在界限明确的出血性占位性病变，怀疑是血管畸形，如海绵体瘤或动静脉瘘，原发性血肿或错构瘤;不太可能考虑包括出血性炎症或出血性原发性或继发性肿瘤。背侧椎板切除术,硬体切开术,中线背侧脊髓切开术用手术显微镜进行，血管病变被确认并切除。手术样本的组织学检查产生纤维蛋白，出血,hematoidin色素，和一些神经组织.尽管在手术期间可以看到内衬壁与血管畸形一致，没有组织学证实这种结构，妨碍病变的明确分类。没有总体或组织病理学证据支持错构瘤或良性肿瘤的诊断。手术后第二天，狗截瘫，伤害性感觉完整。2周内步行恢复。在接下来的12周内，神经功能逐渐完全恢复。在12个月的随访期内，未发现神经功能障碍复发。对于脊髓髓内血管病变的狗，应考虑手术治疗，这些疾病可以取得长期的成功。
