摘　　要：目的探讨不典型脑转移瘤MRI诊断的特点，从而提高不典型脑转移瘤诊断水平及准确性。方法对52例在临床上或病理上已证实的脑转移瘤的MRI表现进行回顾性分析，并总结出其在平扫和增强扫描的MRI征象。结果52例患者中单纯幕上、幕下双侧大脑半球内发现病灶分别为31例、12例，幕上幕下均发现病灶者有7例。其中平扫发现病灶78个，增强后发现病灶139个。结论不典型脑转移瘤MRI表现多样，采用增强扫描可以提高其诊断准确性，具有重要的临床应用价值。Objective To explore the MRI diagnosis characteristics of atypical brain metastatic tumors, and to improve the diagnosis level and accuracy. Methods The performance of MRI in 52 patients with clinically or pathologically brain metastatic were retrospectively analyzed; and summed up the MRI signs in plain and enhanced scan. Results 31 and 12 cases were found lesions by up-screen and down-screen in bilateral cerebral hemispheres of 52 patients respectively. 7 cases were found lesions in both up-screen and down-screen of cerebral hemispheres; and 78 of lesions were found by plain scan, while 139 were found by enhanced scan. Conclusion There are multiple performances of MRI characteristics of atypical brain metastatic. Using enhanced scan can improve the accuracy of the diagnosis. That has important clinical value.
