脑内弥漫性病变的CT诊断

目的显示不同脑内疾病可表现为相似的脑内弥漫性ＣＴ改变，材料与方法：对１５例患者脑ＣＴ平扫与增强扫描，其中包括４种病变，脑囊虫病，脑转移瘤和脑胶质细胞增生，结果：ＣＴ主要改变为脑水肿，脑内弥漫型小强化结节，小囊状低密度灶及阻塞性脑积水，结论：脑内弥漫性系变由多种疾病所致，有时缺乏特征性，为达到正确诊断，重要的是应紧密结合病史，实验室检查及其他影像检查所见进行判断。

CT in the Diagnosis of Diffuse Intracerebral Disease

Objective: To demonstrate that different intracerebral diseases in CT scan might exhibits similar pattern of diffuse intracerebral lesion.Materials and Methods Nonenhanced and contrast enhanced cerebral CT scan were performed in 15 patients. Among them, 4 different diseases were observed, in cluding cerebral cysticercosis, cerebral tuberculosis, metastatic tumor and cerebral gliosis.Results: The chief CT manifestations were cerebral edema, diffuse intracerebral contrast enhanced small nodules, low density cysticfoci and obstructive hydrocephalus.Conclusion: The cause of diffuse intracerebral lesion were multiple, sometimes the CT findings were non specific. In order to approach a proper diagnosis, it is essential to correlate the CT findings with clinical history, laboratory findings and the results of other imaging examination.
