目的:探讨CT对脑转移瘤的诊断价值,提高脑内转移瘤的CT诊断与鉴别诊断的认识.方法:回顾性分析28例经病理或临床确诊的脑转移瘤CT表现.结果:28例中共检出102个病灶;多发19例,占68%;单发9例,占32%;CT平扫呈等、低或等低混杂密度20例,占71%,高密度或高低混杂密度灶8例,占29%;全部病例平扫后均行增强扫描,等密度部分均有中度或明显变化,呈环状或结节样;18例有明显灶周水肿,6例有轻度水肿;19例原发灶在肺,4例原发灶为乳腺癌,2例为鼻咽癌,4例为胃癌.结论:资料表明, CT对脑内转移瘤的诊断与鉴别诊断有可靠的准确性;颅外肿瘤的查找有助于脑内肿瘤的鉴别诊断,特别是肺部的CT检查非常必要.

Objective To investigate the diagnostic value of CT on brain metastasis,and improve CT diagnosis and differential diagnosis of brain metastases.Methods Retrospective analysis of 28 cases confirmed by pathology or clinical manifestations of brain metastatic tumor CT.Results 28 cases with 102 lesions were detected;multiple in 19 cases,accounting for 68%;9 cases with single,accounted for 32%;CT plain scan was 20 cases,low,low density accounted for 71%,high density or mixed high and low density lesions in 8 cases,accounting for 29%;all cases underwent enhanced scan after scanning,density is moderate or significant changes,a ring or nodular;18 cases were peripheral edema,6 cases had mild edema;19 cases of primary tumor in lung,4 cases of primary breast cancer,2 cases of nasopharyngeal carcinoma,4 cases of gastric carcinoma. Conclusion The data show that,CT diagnosis of tumor and differential diagnosis of cerebral metastasis;extracranial tumors to find help for differential diagnosis of brain tumors,especially CT examination of the lungs is very necessary.
