目的 探讨不同分型的布氏杆菌 病性脊柱炎患者影像学表现的差异。方 法 选取我院于2014年1月-2015年3月收 治的34例布氏杆菌病性脊柱炎患者为研 究对象,均经临床和实验室确诊，行腰椎 磁共振成像(MRI)和CT检查。观察记录受 试者MRI及CT检查结果，分析其不同分 型的影像学表现差异。结果 此次入组 的34例确诊布氏杆菌病性脊柱炎患者中 85.3%有牛、羊等牲畜接触史；L4椎体受 累率最高，为58.8%；可根据受试者的 影像学表现差异将其分为椎旁及腰大肌 脓肿型、椎体炎型、椎间盘炎型、附件 炎型和椎旁软组织型等5种类型，其比 例分别为17.6%(6/34)、26.5%(9/34)、 20.6%(7/34)、17.6%(6/34)和 17.6%(6/34)。结论 影像学检查能作为布 氏杆菌病性脊柱炎患者临床分型的有效手 段，以有效节省诊疗时间、提高诊疗效 率，全面改善患者预后。

Objective To investigate the differences of CT and MRI manifestation in different types of brucellar spondylitis. Methods 34 cases of patients with brucellar spondylitis treated in our hospital from January 2014 to March 2015 were selected as the research objects. All were confirmed by clinical and laboratory tests and received lumbar magnetic resonance imaging (MRI) and CT examination. The results of MRI and CT examination were observed and recorded. The differences in imaging findings of different types were analyzed. Results Among the 34 cases of patients with confirmed brucellar spondylitis in this group, 85.3% of them had contact history with cattle, sheep and other livestock. The rate of L4 vertebral body involvement was the highest (58.8%), according to the differences in imaging findings, the subjects can be divided into 5 types, they were paravertebral and psoas abscess type, vertebral inflammatory type, discitis type, adnexitis type and paravertebral soft tissue type,the proportions were 17.6%(6/34), 26.5%(9/34), 20.6%(7/34), 17.6%(6/34) and 17.6%(6/34), respectively. Conclusion Imaging examination can be used as an effective method toidentify the types of brucellar spondylitis, so as to save times for diagnosis and treatment, improve the efficiency of diagnosis and treatment and comprehensively improve the prognosis of patients.
