摘　　要：目的探讨脑内转移瘤的CT表现。方法分析56例临床已证实的脑内转移瘤病例的脑CT征象。结果所有56例病例中,转移灶位于大脑半球42例(其中左侧22例,右侧20例),左右侧小脑7例。单发19例,多发37例。肿块呈结节型40例,平扫呈等密度、高密度、低密度者分别25例、14例、和7例,呈囊实混合型10例。增强后瘤实体部分明显强化47例。瘤周水肿53例,无水肿3例。结论脑内转移瘤CT表现多种多样,增强脑CT扫描是确定有无脑内转移的可靠方法之一。Objective To improve knowledge for the CT features of the metastatic tumors in brain. Methods The CT images of 56 cases uith brain metastatic tumors confirmed by the clinic were retrospectively reviewed. Result In all the 56 cases, the metastatic tumors were located at the cerebral hemisphere in 42 cases (22 cases in the left and 20 cases in the right)and located at the cerebellar hemisphere in 14 cases (7 cases in the left and 7 cases in the right).There were 19 cases with single tumor and 37 cases with multiple ones.The tumors were displayed as anodule in 40 cases and cyst-nodule mixture in 10 cases.In plain CTimages,the nodule's density were equel,high and low in 25 cases,14 cases and 7 cases respectively. After contrast scanning, the tumors had an obvious enhancement in 47 cases. There were edema around the tumors in 53 cases, no edema in 3 cases. Conclusion Plain and contrast CT scanning plays an important role in finding the metastatic tumor in brain.
