例1.患者男,13岁.因T12～L5段严重后凸进行性加重8个月,无法站立伴双下肢疼痛、肌萎缩入院.MRI检查显示L1～L5椎管内占位,考虑为神经元性肿瘤.行L2～L5全椎板切除,于硬膜下摘除9cm×2cm×1.5cm大小实质性肿瘤,病理检查证实神经鞘膜瘤.例2.患者男,10岁.T8～T12段后凸畸形进行性加重伴胸背痛,不全性截瘫7个月,经MRI检查显示T8～10椎管内占位,术后病理学检查证实为胶质细胞瘤.讨论 脊柱的骨化中心约在第10个胎周时开始出现,随着年龄增长,原始骨化中心互相融合,椎体增大,椎间隙则相应变窄,椎体由卵圆形变为长方形,至16岁左右脊柱生长完成,青春期后脊柱的正常曲线方开始固定.脊柱的这种解剖生理特点,决定了少儿椎管内占位与成人椎管内占位在脊柱形态上改变的不同.其主要因素:(1)当椎管内占位性病
Example 1. Patient male, aged 13. Due to progressive aggravation of severe kyphosis of T12 ~ L5 segment for 8 months, it was unable to stand pain and muscle atrophy with bilateral lower extremities and was hospitalized.MRI examination showed that L1 ~ L5 spinal canal space occupying, considered as nerve Metastatic tumors were treated with total L2 ~ L5 laminectomy, and the tumors of 9 cm × 2 cm × 1.5 cm in size were excised from the dura submucosa. The pathological examination confirmed the neurovascular sarcoma.Example 2: Male, 10 years old, T8 ~ T12 Kyphosis deformity with chest pain, incomplete paraplegia 7 months, MRI examination showed T8 ~ 10 spinal canal space occupying the postoperative pathological examination confirmed as glioblastoma.Discussion of the ossification center of the spine Began to appear on the tenth week, with age, the original ossification center fusion, vertebral enlargement, the corresponding intervertebral space narrowing, the vertebral body from the oval to rectangular, until the age of 16 spine growth Complete, adolescent spine normal curve began to be fixed.The anatomical and physiological characteristics of the spine, determines the pediatric spinal canal occupancy and adult spinal canal occupying changes in the shape of the spine.The main factors: (1) When the spinal canal space-occupying disease
