228 stereotactic biopsies for the diagnosis of brain lesions were evaluated. In 98.2% a diagnosis could be established. The diagnosis was made of brain tumor in 79.3%, of brain abscess in 7.5% and of encephalitis in 3.5% of cases. In 2.2% of the patients a pathological finding was obtained without a clear histological definition. No histological diagnosis could be made in 1.8% of the patients. A severe complication of brain biopsy occurred in 2.2% of the patients (1 death, 1 abscess, 3 increased impairments). The stereotactic procedure appears to have a low mortality and morbidity, and to be highly accurate.
对228例用于诊断脑病变的立体定向活检进行了评估。98.2%的病例能够确诊。诊断为脑肿瘤的占79.3%，脑脓肿的占7.5%，脑炎的占3.5%。2.2%的患者获得了病理结果，但组织学定义不明确。1.8%的患者无法做出组织学诊断。2.2%的患者发生了严重的脑活检并发症（1例死亡，1例脓肿，3例功能障碍加重）。立体定向手术似乎死亡率和发病率较低，且准确性高。
