脑转移瘤67例CT分析

CT Analysis of 67 Cases of Intracranial Metastatic Tumors

目的 回顾性分析 6 7例经手术和病理证实的颅内转移瘤的CT表现 ,为脑转移瘤定性诊断提供依据。方法 男 48例 ,女 19例 ;均经CT平扫及增强扫描。结果 6 7例脑转移瘤中 5 4例呈颅内多发转移 ,占 80 .5 % ,单发转移 13例 ,两者差别显著 (P <0 .0 1) ;增强前发现瘤灶 15 6个 ,增强后发现 2 17个 ,增强前后差异显著 (P <0 .0 1) ;瘤灶位于幕上的有 2 0 9个 ,占 96 .3% ,位于其他位置的 18个 ,两者有明显差异 (P <0 .0 1)。结论 颅内转移瘤以肺癌为主 ,且以男性居多 ;颅内转移通常为多发病灶 ,对于肿瘤患者尤其是肺癌患者 ,无论有或没有临床神经和精神症状 ,行颅脑CT扫描都应以增强扫描为首选。

Purpose We have studied CT appearances of 67 intracranial metastatic tumors. Thus we put forward several reliable CT signs and rules for the qualitative diagnosis and distinguish diagnosis. Methods A retrospective statistic study was performed after all clinical information transformed into qualitative data. Results 54 patients had intracranial multiple focal metastatic lesions while the rest 13 patients had single lesion( P <0.01). After enhancement, 61 more focal lesions were found, which is of great significance. Conclusion Lung cancer stood most of the primary tumor which was prone to metastasize intraranially and the male seemed more liable to it. The patients always had multiple metastatic lesions and CT enhancement scan would help to detect the lesions that CT plain scan could not find. When the patients who suffered from tumor, especially lung cancer came to have the head CT examination, we suggest the enhancement CT scan be the prior choice, which is of great significance in the early phase diagnosis, prognosis and therapeutic policy of the patients.
