目的: 观察磁共振成像对布氏杆菌性脊柱炎(brucella spondylitis, BS)的诊断及蒙医对BS治疗的效果。方法: 以本院收治的50例急性期BS患者作为研究对象,通过应用蒙医药治疗,分别对其治疗前后实施磁共振扫描,分析脊柱病变与周围组织影像学特点。结果: 布氏杆菌感染腰大肌后磁共振成像结果为T1WI、T2WI各呈低信号、高信号,病变组织以及其附近正常组织分界不清晰。椎旁软组织磁共振成像结果为T1WI、T2WI各呈低信号、高信号。椎旁脓肿、硬膜外脓肿一般出现于患者受累的椎体组织,且患者的脓肿壁在磁共振成像显示为T1WI等信号,而T2WI为高信号。脓肿腔内部T1WI、T2WI分别显示低信号与高信号。蒙药治疗后,早期脊柱及周围软组织病变范围缩小。结论: 磁共振成像用于BS患者的诊断,不仅可以掌握患者病变椎体形态、感染以及腰椎受累等情况,还可明确椎旁脓肿与硬膜外脓肿范围,为疾病在后期治疗用药奠定基础。
Objective: To observe the diagnostic value of magnetic resonance imaging in brucella spondylitis(BS) and the effectiveness of Mongolian medicine treatment. Methods: Fifty patients with acute BS were treated as the research object, and all of them were treated with Mongolian medicine. Magnetic resonance scanning was performed before and after treatment to analyze the imaging characteristics of spinal lesions and surrounding tissues. Results: After Brucella infection of psoas major, magnetic resonance imaging showed low signal and high signal on T1WI and T2WI; the results of paravertebral soft tissue imaging showed low signal and high signal on T1WI and T2WI. The boundary between the lesion tissue and its adjacent normal tissue was not clear. Paravertebral abscess and epidural abscess generally appeared in the affected vertebral tissue, and the abscess wall of the patient showed equal signal on T1WI and high signal on T2WI on magnetic resonance imaging. T1WI and T2WI in the abscess cavity showed low signal and high signal, respectively. After treatment with Mongolian medicine, the range of early spinal and surrounding soft tissue lesions was reduced. Conclusion: In the diagnosis of patients with BS, magnetic resonance imaging can not only grasp the shape of the diseased vertebral body, infection and lumbar involvement, but also clarify the range of paravertebral abscess and epidural abscess, laying a foundation for the later treatment of the disease.
