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。
Objective To investigate the relationship between atypical brain abscess and its pathology and the causes of misdiagnosis, and to raise awareness of atypical brain abscess. Methods The clinical manifestations and imaging features of 33 patients with pathologically confirmed brain abscess were analyzed retrospectively. Results 17 cases were misdiagnosed as glioma, metastasis and cerebral cysticercosis. Encephalitis and suppurative easily misdiagnosed. Conclusions The main reason for misdiagnosis is lack of understanding of atypical brain abscess and over-reliance on imaging techniques. Atypical brain abscess need not rush to surgery.
