目的总结儿童髓内肿瘤的病理特点、显微手术和治疗效果,并进行探讨。方法81例儿童脊髓内肿瘤均经手术切除和病理证实,对手术治疗的效果进行回顾性分析。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,不同的病理类型的肿瘤,切除率不同。放疗用于高度恶性的肿瘤。椎板复位术可以有效地减少脊柱畸形的发生率。结论大多数的髓内肿瘤组织学上为低级别星形细胞瘤(Ⅰ~Ⅱ级)、室管膜瘤和胚胎残余组织肿瘤,积极手术切除能够获得满意的疗效。
Objective To summarize the pathological features, microsurgery and therapeutic effects of intramedullary neoplasms in children. Methods 81 cases of children with spinal cord tumors were confirmed by surgical resection and pathology, the effect of surgical treatment were retrospectively analyzed. Results Child intramedullary tumors were more common in 24 cases (29.6%) of astrocytomas, 13 cases (16.0%) of ependymomas and 11 cases (13.6%) of epidermoid cysts. The rates of resection different. Radiotherapy for highly malignant tumors. Vertebral plate reduction can effectively reduce the incidence of spinal deformity. Conclusions Most intramedullary tumors are histologically low grade astrocytomas (grade Ⅰ ~ Ⅱ), ependymoma and residual tissue tumor of the embryo. Successful surgical resection can achieve satisfactory results.
