回顾性总结分析22例巨大哑铃形椎管内肿瘤的治疗经验。22例肿瘤中获全切21例，次全切1例，无手术死亡。提出不同节段哑铃形椎管内肿瘤有其临床特点，早期诊断可提高疗效，MRI对其有确切定位及较好定性诊断，尽早实施显微手术及良好的术后护理，是获得手术成功的关键。

颅脑手术戒毒这项新的医疗技术在社会上引起很大反响，最近被卫生部紧急叫停。从颅脑手术戒毒的历史、存在的 问题、哲学及伦理方面进行反思是有必要的。把一项临床科研项目直接变换成一项临床服务项目，既未经严格科学论证也不符合伦理与法规要求。

儿童颅脑枪弹伤为一种特殊类型的损伤，其诊断和处理都有特殊性[1]，国内文献极少报道。我科从1985～1997年共收治15例儿童颅脑枪弹伤，总结分析如下。

Background: Lymphangioma of the soft tissue is not uncommon. However, as far as the authors know, intraspinal lymphangioma is clinically rare and very few cases have been reported previously. Methods: Two patients who had backache and acratia of the lower limbs and difficulty in relieving themselves were examined by plain radiography and magnetic resonance imaging before surgery. Treatment consisted of the usual technique of surgical resection of the tumor microscopically. Histological examination of the resected material confirmed the diagnosis. Postoperative follow-up assessment was performed by magnetic resonance imaging. Results: Intraspinal lymphangioma is very rare clinically and its cause remains controversial. Magnetic resonance imaging can obtain precise position fixing, but it is hard to make preoperative qualitative determination. The most effective treatment of intraspinal lymphangioma is to excise it totally. Conclusions: The clinical appearance of intraspinal lymphangioma has no character. Magnetic resonance imaging is important in diagnosing it. The most effective treatment of intraspinal lymphangioma is to excise it totally. Further observation is recommended because of the possibility of local recurrence.
