儿童脊髓内肿瘤81例

Eighty-One Cases of Pediatric Intramedullary Tumors

目的总结儿童脊髓内肿瘤的病理特点、临床表现和手术治疗效果,探讨其特点和规律。方法81例儿童髓内肿瘤均经显微手术切除和病理证实,进行回顾性分析。结果儿童髓内肿瘤以星形细胞瘤24例(29.6%)、室管膜瘤13例(16.0%)和表皮样囊肿11例(13.6%)为多见,其运动系统损害是儿童髓内肿瘤最常见首发症状,其次为疼痛、感觉障碍、括约肌功能障碍等。放疗用于高度恶性肿瘤。椎板成形术可以有效减少脊柱畸形发生率。结论运动系统损害是儿童髓内肿瘤最常见首发症状,感觉障碍较成人发生率低。积极手术切除能获得满意疗效。

Objective To summarize the pathology, clinical presentations, microsurgical treatments and to investigate the rules of pediatric intramedullary tumors. Methods Eighty- one patients with pediatric intramedullary tire,ors proved by histopathology were treated by mierosurgery, which were analyzed retrospectively. Results Astrocytomas（29.6 % ）, cpendymomas （ 16.0 % ）, cpidcrmoids （ 13.6 % ） could be frequently scen in pediatric intramedullary tumorss. Motor function damage was frequent. Next was pain, sense damage and sphincter dysfunction. Radiotherapy was used on malignant tumors after operation. Laminoplasty can effectivcly decrease the rate of spinal deformities. Conclusion Motor funct ion demage is the most common symptoms, and sense damage is lower than adult, and radical microsurgcry can obtain satisfactory results.
