目的分析布氏杆菌性脊柱炎的核磁共振成像(MRI)特点,以提高布氏杆菌性脊柱炎的早期诊断率。方法回顾性分析经临床证实的12例布氏杆菌性脊柱炎患者MRI平扫和增强的特点。结果 12例患者病变部位:腰椎10例,腰骶椎同时受累2例。9例椎体形态基本正常,3例椎体前缘轻度楔形变。5例患者椎间盘信号明显异常伴椎间隙轻度变窄。3例椎旁可见条状或梭形异常信号影,位于椎前、两侧或椎体后方,位于椎体后方压迫硬膜囊及神经根,脓肿局限,没有流注现象。脓肿壁不规则强化,中心不强化;4例椎旁软组织表现为增厚、肿胀,未见脓肿形成;5例椎旁软组织未见明显异常信号。4例表现为椎体表面不够平整,边缘存在骨赘,且相邻骨赘之间具有融合的倾向。3例椎小关节骨质破坏,关节面模糊。结论采用MRI对腰骶椎布氏杆菌性脊柱炎早期诊断具有重要的意义,在临床中值得大力推广。
Objective To analyze the magnetic resonance imaging (MRI) features of brucellosis spondylitis to improve the early diagnosis rate of brucellosis spondylitis. Methods Retrospective analysis of 12 patients with clinically proven brucellosis spondylitis MRI features of MRI plain and enhanced. Results The lesions of 12 patients were lumbar in 10 cases and lumbosacral vertebra in 2 cases. 9 cases of vertebral body morphology was normal, 3 cases of mild frontal wedge deformation. In 5 patients, the intervertebral disc signal was significantly abnormal and the intervertebral space was slightly narrowed. Three cases of paravertebral visible strip or fusiform abnormal signal, located in the anterior vertebrae, both sides or posterior vertebral body, located in the posterior vertebral body dural sac and nerve root compression, abscess limitations, there is no streaming phenomenon. Irregular abscess wall enhancement, the center is not enhanced; 4 cases of paravertebral soft tissue showed thickened, swollen, no abscess formation; 5 cases of paravertebral soft tissue showed no significant abnormal signal. 4 cases showed that the vertebral body surface is not smooth enough, the edge of osteophytes, and adjacent osteophytes tend to have a fusion between. 3 cases of vertebral facet joint destruction, articular surface blurred. Conclusion The MRI diagnosis of lumbosacral vertebral brucellosis is of great significance in the early diagnosis and should be greatly promoted in clinic.
