目的探讨布氏杆菌脊柱炎(BS)的MRI表现,以提高对该病的认识及诊断水平。方法回顾性分析经临床及实验室确诊或手术病理证实的57例BS患者的MRI平扫及增强扫描影像表现。结果 40例行MRI平扫加增强扫描,17例MRI平扫,累及骶椎10例(17%),腰椎52例(91%),胸椎8例(14%),颈椎3例(5%),“跳跃性”发病4例(7%)。BS可侵犯脊柱任何部位,以腰椎多见,椎体边缘“虫蚀”样骨质破坏,可伴有骨质增生,椎体形态多无明显变化,椎间盘炎性改变较轻,椎间隙无或轻度狭窄,椎旁、椎管内硬膜外脓肿及腰大肌脓肿显示清楚;大部分病例可见腰背部肌肉肿胀及皮下水肿征象。结论 MRI影像表现在诊断及鉴别诊断BS方面具有较高的价值。
Objective To investigate the MRI manifestations of brucellosis (BS) in order to improve the understanding and diagnosis of this disease. Methods Retrospective analysis of 57 patients with BS confirmed clinically and laboratory confirmed by pathology or MRI showed enhanced MRI and enhanced imaging. Results Forty patients underwent MRI scan and MRI scan. Seventeen patients underwent MRI scan, including 10 sacral vertebrae (17%), 52 lumbar vertebrae (91%), 8 thoracic vertebrae (14%) and 3 cervical vertebrae (5% , “Jumping” “onset in 4 cases (7%). BS can invade any part of the spine to the lumbar more common, vertebral edge ”worm eclipse " like bone destruction, may be associated with bone hyperplasia, vertebral body shape no obvious changes, less disc inflammatory changes, intervertebral space No or mild stenosis, paravertebral, intraspinal epidural abscess and psoas abscess showed clear; most cases showed low back muscle swelling and signs of subcutaneous edema. Conclusion MRI findings are of high value in the diagnosis and differential diagnosis of BS.
