颅内转移瘤的CT表现

THE CHARACTERISTICS OF INTRACRANINAL METASTATIC TUMOR IN CT

本文分析了22例颅内转移瘤的CT表现。本文资料显示，以肺癌颅内转移最为常见，（77．3％），颅内转移瘤CT平均呈等，低密度居多（87．4％），并伴有明显的水肿带为特征。作者提出本组颅内转移瘤单发多于多发，与文献报告不一致，考虑与CT机的扫描分辨率有关。对原发灶已明确诊断，CT检查未显示明确的颅内转移瘤病灶，但有明显水肿，仍应考虑颅内转移瘤可能，增强扫描可提高颅内转移瘤的准确率。

In this paper,the CT expression of intracraninal metastatic tumor in 22 patients is reported. It was observed that the characteristics in majority are normal or low density accompanied by distinct band of edema. It is different with the results reported on other articles that singu1ar ones more than multi foed in these patients,this may be relation ones with distinguishable rate of CT. Writers think that the patients with distinct band of ederna in brain and primary tumor determied but no sure focus of intracraninaI metastatic turnor have also Possibitity of intracraninal metastatic tumor. The intensive CT scan may increase the diagnostic rat of Intracraninal metastatic tumor.
