椎管内髓外肿瘤的CT扫描分析

The Spinal Canal Tumor CT Scans the Myelin Analysis

目的:通过CT扫描对椎管内髓外肿瘤进行诊断,明确肿瘤的位置及与周围组织结构的关系,为临床治疗提供可靠的依据。方法:采用CT平扫和甲泛葡糖脊髓造影CT扫描(CAM),观察蛛网膜下腔,扫描平面与椎管轴平面平行,观察椎管各段有无病灶存在。结果:髓外硬膜内肿瘤11例,其中神经鞘瘤4例,脊膜瘤3例,神经纤维瘤2例,畸胎瘤2例;硬膜外肿瘤6例,其中神经鞘瘤3例,神经纤维瘤2例,蛛网膜囊肿1例。17例椎管内髓外肿瘤均通过手术病理证实。结论:CT平扫和甲泛葡糖脊髓造影CT扫描可对椎管内髓外肿瘤作定位诊断,能明确肿瘤与周围组织结构的关系,为临床治疗提供了可靠的依据。

Objective：By CT scan of the spinal canal tumor diagnosis,pulp outside the location and clear tumor with the surrounding tissue structure, the relation between the for a reliable basis for clinical treatment.Methods：Using CT flat esau andcomputer-assisted myelography spinal cord angiography CT scans （CAM）,observe subarachnoid,scanning plane and planar parallel axis,observing intradiscal paragraphs without lesions were present.Results：Pulp outside intradural tumor in 11 cases,including schwannomas in 4 cases,present a tumor 3 cases,nerve fibroma in 2 cases,teratoma in 2 cases,Epidural tumor 6 patients,including schwannomas in 3 cases,nerve fibroma in 2 cases,arachnoid cysts in one. 17 cases of the spinal canal tumor were surgically outside medullary pathology.Conclusion：CT flat esau and armour pan mercapto-acetic spinal cord angiography CT scan of the spinal canal tumor pith outside,can make clear tumor location diagnosis with the surrounding tissue structure,the relation between the for clinical treatment provides the reliable basis.
