颅内脊索瘤是一种少见的低度恶性肿瘤,起源于残余的胚胎脊索组织。据文献报道,约占颅内全部肿瘤的0.1～0.55％。在我院经CT检查,并经手术病理证实的800例颅内肿瘤中占0.63％。现将我们遇到的5例报告如下。 一般资料 本组5例,女4例,男l例。年龄20～54岁。均经颅脑CT检查,并分别作了增强前、后(增强剂用60％泛影葡胺,以每kg体重1.5ml静脉注射)横断扫描和增强后冠状面扫描。层厚为10mm,人均扫描3次。5例头颅平片中2例蝶鞍扩大,前、后床突、鞍背及枕骨斜坡骨质有不同程度破坏并钙化,1例蝶鞍大小及骨质正常,1例蝶骨大、小翼骨质均破坏。3例行颈内动脉造影,有1例提示鞍区偏左有肿
Intracranial chordoma is a rare, low-grade malignant tumor that originates from residual embryonic chordal tissue. According to the literature, accounting for about 0.1 ~ 0.55% of all intracranial tumors. In our hospital by CT examination, and confirmed by surgical pathology of 800 cases of intracranial tumors accounted for 0.63%. Now we have met five cases are as follows. General information The group of 5 patients, 4 females, male l cases. Age 20 to 54 years old. All of them were examined by cranial CT and transected and enhanced coronal scan were performed before and after enhancement (60% of diatrizoate with reinforcing agent, 1.5ml / kg body weight intravenously). Layer thickness of 10mm, per capita scanning 3 times. 5 cases of cranial plain film in 2 cases of sella enlargement, anteroposterior and posterior bed, saddle and occipital slope of the bone have varying degrees of destruction and calcification, 1 case of sella size and normal bone, 1 case of sphenoid big and small wing Bones are destroyed. 3 cases of internal carotid artery angiography, 1 case prompted the left side of the saddle swollen
