摘要
目的探讨肺癌脑转移的MRI表现,提高认识和诊断水平。方法回顾性分析164例经病理证实的肺癌患者脑转移的MRI表现,分析转移病灶的部位、数目、形态、大小、水肿程度等,同时分析不同病理学类型肺癌脑转移的MRI表现。结果所有肺癌脑转移患者中,单发病灶47例,多发病灶117例。共有257个转移灶,大多分布在幕上(73.2%)。灶体直径≥1cm,多表现为中、重度水肿(68.8%)。腺癌脑转移病灶以中度、重度水肿比例最高(68.2%)。结论肺癌脑转移灶具有典型脑转移瘤的MRI特征,有利于临床早期干预。
Objective To explore the MRI features of brain metastases of lung cancer in order to improve the knowledge and diagnostic accuracy rate. Methods MRI characteristics of 164 patients with brain metastases of lung cancer which proven by pathology were reviewed retrospectively. The location, size, shape, peri-tumoral edema were analyzed. The relationship between MRI characteristics of brain metastasis and pathological type also analyzed. Results Of the 164 patients, 47 cases had solitary lesion, 117 cases had multiple metastases. In 257 metastases, most of it （73.2%） distributed in supratentorial. 68.8%of metastases which were larger or equal to 1cm showed moderate or serious peri-tumoral edema. Moreover, brain metastasis from adenocarcinoma performed with high rates （68.2%） in moderate or serious peri-tumoral edema. Conclusion MRI imaging could obviously reflect the characteristics of brain metastases of lung cancer. It is benefit for the clinical early intervention.
