[Clinical value of MRI in the diagnosis of Brucellosis spondylitis].
Objective: To analyze the MRI characteristics of Brucellosis spondylitis (BS) and evaluate the clinical value of MRI in the diagnosis of BS. Methods: A total of 47 patients clinically diagnosed as BS from General Hospital of Jizhong Energy Xingtai Mining Industry Bloc and Xingtai Second Hospital from January 2015 to December 2017 were collected, including 32 males and 15 females, aged 24-77 years, with an average age of (57±11) years, and the course of disease was 1 month-2 years. Routine spinal MRI sequence were acquired for patients. Images were assessed by two senior imaging diagnostic physician independently. The evaluation included signal changes in the affected area of the vertebral body, vertebral body and intervertebral disc, the signal of paravertebral soft tissue, the signal of abscess around the vertebral body, whether the dural sac, spinal cord and nerve root were compressed or not, and its signal changes. Results: (1) Spinal involvement, in 47 patients with BS, 112 vertebral bodies were involved, including 11 cervical vertebrae (9.8%), 5 thoracic vertebrae (4.5%), 91 lumbar vertebrae (81.2%), and 5 sacral vertebrae (4.5%), the lumbar vertebrae was dominant. (2) MRI features, 112 vertebral bodies were involved, including 105 (93.8%) vertebral bodies morphology showed no significant changes, only 7 (6.2%) vertebral bodies showed mild collapse changes; 71 vertebral bodies showed diffuse destruction (63.4%), and 41 vertebral bodies showed localized destruction (36.6%). Among the 47 cases, 40 cases were continuous destruction of adjacent vertebral bodies, 6 cases showed non-adjacent damage; 37 cases of intervertebral disc involvement; 29 cases of narrowing of intervertebral space; 11 cases of paravertebral soft tissue swelling and 28 cases showed paravertebral abscess. Conclusion: MRI has certain characteristics in the diagnosis of Brucella spondylitis and has a high clinical value in the differential diagnosis of spinal disease.
