手术证实的非典型脑脓肿33例分析

目的 探讨非典型脑脓肿影像与病理的关系及误诊的原因，提高对非典型脑脓肿的认识。方法 对33例手术后病理证实的脑脓肿患者的临床表现、影像特点进行回顾性分析。结果 17例误诊为胶质瘤、转移瘤和脑囊虫等。脑炎期和化脓期容易误诊。结论 误诊的主要原因是对不典型脑脓肿的认识不足，过分依赖影像学技术，非典型脑脓肿不必急于手术治疗。

Clinical analysis of 33 patients with atypical brain abscess confirmed by operation

Objective To explore the relationship between brain imaging and histopathology and to find out the causes of misdiagnosis in the patients with brain abscess.Methods Clinical manifestation and imaging of 33 patients with brain abscess confirmed by pathological findings after operation were analyzed retrospectively.Results Seventeen patients were misdiagnosed as glioma and metastasis and cysticercosis.Especially easier in the encephalitic and purulent phases.Conclusions The main reasons of misdiagnosis are laking of thorough knowledge of atypical brain abscess and depending excessively on radiographic findings.
