脊髓内胆脂瘤的诊断和手术治疗

目的提高脊髓内胆脂瘤的诊断水平及选择治疗方法。方法总结１９７８～１９９５年收治的经手术和病理证实的１０例脊髓内胆脂瘤的经验。结果患者临床表现无特异性。本组ＣＴ检查８例，显示肿瘤呈现均匀低密度影像，边界清楚，强化扫描多无增强。ＭＲ检查４例，肿瘤呈现信号强度变化不定的特点，边界清楚。１０例患者均行手术治疗，肿瘤全切除１例，次全切除９例。８例术后得以随访，无复发。结论肿瘤全切是治疗本病的最好选择。

Diagnosis and surgical treatment of intramedullary epidermoid cyst of the spinal cord

Objective To discuss clinical diagnosis and surgical treatment of intra medullary epidermoid cyst.Methods Ten intramedullary epidermoid cysts were confirmed by operatively and pathologically from 1978 to 1995.Results The tumors were located in the spinal cord. Clinical presentation of this tumor was not specific. On CT scans, eight tumors were characterized by a homogenous low density lesion and well defined limits. They usually did not enhance with contrast medium. On MR imaging, four tumors were characterized by an important variability of signal intensity,well defined limits.All patients underwent resections of epidermoid cyst, 1 total resection,and 9 subtotal resections. Eight cases were followed up from half a year to seven years. No case recurred.Conclusion Total resection of epidermoid cyst is the best choice.
