摘　　要：目的:探讨布氏杆菌性脊柱炎的MRI及CT表现,以提高该病的诊断水平。方法 :回顾性分析已确诊的43例布氏杆菌性脊柱炎的MRI及CT表现。结果:143例行MRI扫描,检出椎体炎32例,表现为椎体内大片状异常信号影24例,8例椎体边缘小斑片影;椎间盘炎及终板炎10例;2例骶髂关节面异常信号;23例合并有椎旁受累。219例行CT检查,其中椎体破坏11例,表现为椎体周缘小破坏灶、边角缺如、大片状缺损等,病灶周边增生硬化;椎间盘炎伴膨出8例;合并椎小关节面增生硬化4例,骶髂关节炎1例。3累及单个椎体5例(11.6%),2个及2个以上椎体受累30例(69.8%);腰椎病变32例,以L_4、L_5椎体发病率最高(53.1%)。结论:布氏杆菌感染致脊柱炎有较为特征的CT及MRI表现,对于侵及椎体的早期病变,MRI检出率优于CT。Objective： To study MRI and CT findings of brucellar spondylitis caused and to improve lever of the clinical diagnosis. Methods： We analyzed CT and MRI findings of 43 patients with brucellar spondylitis retrospectively. Results： 1Forty-three patients underwent routine MRI scan. There were 32 cases of vertebral bodies, a large patch of abnormal signal of vertebral body shadow 24 cases, 8 cases of vertebral body margin small patch shadow; Intervertebral disc inflammation and endplate inflammation in 10 cases; 2 cases of sacroiliac joint surface anomaly signal; 23 lesion beside of vertebral body. 2Ninteen patients underwent CT examination, including vertebral body destruction in 11 cases, vertebral peripheral small focal damage, a large patch of defects, edge horn were absent, hyperplasia of lesions around the hardening; Intervertebral disc inflammation and bulging with 8 cases; 4 cases merge vertebral hyperplasia of small joint surface hardening, 1 case of sacroiliac arthritis. 3Five cases involved one vertebral body（11.6%）, two or more vertebral bodies involved in 30 cases（69.8%）, 32 cases in the lumbar spine, L_4, L_5 vertebral rate was highest（53.1%）. Conclusion： CT and MRI findings in brucellar spondylitis are characteristic. Comparing to CT, detectable rate of MRI is higher, especially in early stage of cases with vertebral body affected.
