布氏杆菌性脊柱炎在低场MRI的表现分析

Analysis about findings of spondylitis caused by Brucells infection in low field MR

目的:初步探讨布氏杆菌性脊柱炎的临床表现及低场MRI的图像特点,从而提高对该病的认识及诊断水平。方法:搜集6例布氏杆菌性脊柱炎患者的MRI资料并回顾文献报道。结果:以下腰椎感染机会较多,以L_(4～5)发病率最高,受累椎体多伴有明显骨质增生,反应性增生明显。结论:在低场MRI下,布氏杆菌感染引起的脊柱炎具有一定的特征性表现,鉴别诊断应包括脊柱结核和化脓性脊柱炎。

Objective：To investigate low field MR findings of spondylitis caused by Brucells infection and to improve the clinical diagnosis. Methods： 6 cases with spondylitis caused by Brucells infection collected were taken with MR and reviewed of literature. Results： It was found that MR findings of these cases with spondylitis appeared most frequently in the lower lumbar spine than other spine with bony hyperostosis intensely, especially in the L4 -5 vertebral bodys. It appeared hyperostosis intensely reactively. Conclusion： Low field MR findings of spondylitis caused by Brucells infection is characteristic. Differential diagnosis should include spinal tuberculosis and pyogenic spondylitis.
