A 3-year, 9-month-old Bernese Mountain dog presented with a 10-day history of acute right hemiparesis. Neurological examination indicated abnormalities in the C1-C5 spinal segments. Magnetic resonance imaging (MRI) revealed an epidural mass at C3-C4, which was surgically removed after dorsal laminectomy. The neurological signs were completely resolved by the 12th postoperative day. The lesion was diagnosed as an inflammatory pseudotumor on histopathological examination. Another MRI performed 63 days after surgery showed no lesion regrowth, and there has been no recurrence for approximately 6 years. Reports of inflammatory pseudotumors are rare, and their treatment remains unclear. Previous reports and the course of this case suggest that a good prognosis may be achieved if complete surgical resection of an inflammatory pseudotumor arising in the epidural region can be accomplished.
一只3岁9个月大的伯恩山犬出现了10天的急性右侧偏瘫病史。神经系统检查显示C1 - C5脊髓节段存在异常。磁共振成像（MRI）显示C3 - C4水平有一个硬膜外肿块，在进行背侧椎板切除术后将其手术切除。术后第12天神经症状完全消失。组织病理学检查将该病变诊断为炎性假瘤。术后63天进行的另一次MRI检查显示病变无复发，并且在大约6年的时间里没有再次出现。炎性假瘤的报道很少，其治疗方法仍不明确。既往报道及该病例的病程表明，如果能对硬膜外区域出现的炎性假瘤进行完整的手术切除，可能会取得良好的预后。
