总结了１００例经病理和临床证实的脑转移瘤，来自于至少１５种不同的原发癌，其中以肺癌最多（６５％），单发４８例，多发５２例。分布部位以顶叶最多（７４／２１１），额、颞叶次之。着重分析了脑转移瘤ＣＴ表现的特点：①平扫时，高、等、低和混杂密度均有；②增强扫描，以结节状多见，其次为环形、混合型；③灶周水肿多范围广泛，但水肿程度不与病灶大小成正比；④脑转移瘤多位于两侧大脑皮层下区，乳腺癌脑转移也不例外。各类型肺癌的脑转移与其它原发癌的脑转移之间在ＣＴ表现上并无显著差异。文中指出了增强扫描的重要性，但平扫还是必要的；讨论了脑转移瘤与其它病变尤其是胶质瘤和脑膜瘤的鉴别诊断，强调了紧密结合临床的重要性。
A total of 100 pathologically and clinically confirmed brain metastases were summarized from at least 15 different primary cancers, of which lung cancer was the highest (65%), solitary 48, and multiple 52. Distribution to the parietal lobe up (74/211), the amount of temporal lobe. Focus on the analysis of brain metastases CT features: ① plain scan, high, low, and hybrid density are; ② enhanced scan to more common nodules, followed by ring, mixed type; ③ perifocal edema and more A wide range, but the degree of edema is not proportional to the size of the lesion; ④ brain metastases are mostly located on both sides of the cerebral cortex, breast cancer is no exception. There was no significant difference in CT findings between brain metastases of all types of lung cancer and those of other primary cancers. The article pointed out the importance of enhanced scanning, but plain scanning is still necessary; discusses the differential diagnosis of brain metastases and other lesions, especially gliomas and meningiomas, emphasizing the importance of close clinical integration.
