摘要
通过对21例CT平扫和增强扫描均呈低密度病灶的脑胶质细胞瘤进行临床、手术和病理分析,结果显示低密度不强化脑胶质细胞瘤的误诊原因主要是:较长的病史、非特异性的症状和很少的体征。造成初诊时针对性不强,观察和对症治疗时间过长。这类病人首发症状最常见为癫痫,多以颅内压增高,视力减退就诊。病理诊断多属Ⅰ级,少数为Ⅰ~Ⅱ级星形细胞瘤和胶质细胞增生。手术切除疗效有限,复发和恶化率高。
We analyse the clinical,operational and pathological characters of 21 gliomas patients,whose general and enhanced CT scannings show low density pathospot and which can be falsely diagnosed easily.The reasons include:long case history,nonapecific symptom and therapy.These patients,initial complains are epilepsy with intracranial hypertension and decreased eye sight,Most pathological diagnoses are astrocytoma(class I),some are classⅠ~Ⅱand for gliocytes proliferation the operative effect is limited and there,s a high reoccurance and aggravation rate.
