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L4、L5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。
Abstract
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, L4, L5 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.
