脑干肿瘤治疗的选择有赖于准确的诊断。因为大多数脑干肿瘤不能手术切除,立体定向活检便成为获得病理组织的一种有吸引力的方式。 作者对1983年11月到1993年12月间在Florid大学24例中脑、桥脑或延髓占位病变的病人进行了25次立体定向手术。其中男性10例,女性14例,年龄在3—68岁之间。所有病人术前均做了CT增强或不增强扫描,大多数病人做了MRI,部分病人做了血管造影,这些病变有11例位于桥脑,6例 The choice of brain stem tumor treatment depends on accurate diagnosis. Because most brain stem tumors cannot be surgically removed, stereotactic biopsy is an attractive way to obtain pathological tissue. The authors performed 25 stereotactic operations on 24 cases of midbrain, pons or medulla oblongata lesions at Florid University between November 1983 and December 1993. Among them, there are 10 males and 14 females, aged between 3 and 68 years old. All patients underwent preoperative or non-enhanced CT scans. Most patients performed MRI. Some patients performed angiography. 11 of these lesions were located in the pons, and 6 were found.
