目的：进一步探讨脑脓肿发病情况、影像学表现，选择最佳治疗方法，提高治疗效果。方法：回顾分析１４７例脑脓肿的发病、病因、影像学表现、治疗方法及死亡率下降因素。结果：脑脓肿发病年龄较年青，血源性及隐源性脑脓肿发病率升高，ＣＴ结合ＭＲＩ可明确诊断，选择最佳手术方法。ＣＴ应用后死亡率由２３８％下降到７５％。结论：ＣＴ为脑脓肿最主要的诊断方法，ＣＴ定位下穿刺排脓可治愈大部分脑脓肿。
Objective: To further explore the incidence of brain abscess, imaging findings, choose the best treatment and improve the therapeutic effect. Methods: Retrospective analysis of 147 cases of brain abscess incidence, etiology, imaging findings, treatment and mortality factors. Results: The incidence of brain abscess was younger, the incidence of blood-borne and cryptogenic brain abscess was higher. CT combined with MRI could confirm the diagnosis and choose the best surgical method. The mortality rate after CT application decreased from 23.8% to 7.5%. Conclusion: CT is the most important method for the diagnosis of brain abscess. The CT abscess can cure most brain abscesses.
