对２７例经手术和病理证实的椎管内胆脂瘤患者的临床资料进行分析。发现患者的临床表现无特异性；ＣＴ检查示肿瘤呈均一低密度影，边界清楚，强化扫描多无增强；ＭＲ检查示肿瘤信号强度变化不定，边界清楚。２７例患者均行手术治疗，肿瘤全切６例、次全切除１７例、大部切除４例；术后对２３例随访０．５～７年，２例复发，均再次行手术治疗后好转。表明ＣＴ和ＭＲ检查有助于椎管内胆脂瘤的术前诊断，显微镜下全切是治疗本病的最好选择。
Clinical data of 27 patients with cholesteatoma confirmed by surgery and pathology were analyzed. The clinical manifestations of the patients were found to be nonspecific. The CT findings showed that the tumors showed a uniform low-density shadow with clear boundary and no enhancement of the enhancement scan. MR examination showed that the tumor signal intensity varied and the border was clear. Twenty-seven patients underwent surgical resection. Tumor resection was performed in 6 cases, subtotal resection in 17 cases and subtotal resection in 4 cases. Twenty-three cases were followed up for 0.5-7 years and 2 cases were relapsed after operation. . Show CT and MR examination is helpful for preoperative diagnosis of spinal cholesteatoma, under the microscope is the best choice for the treatment of this disease.
