【摘要】：目的:探討單發(fā)腦轉(zhuǎn)移瘤(SBM)的磁共振表現(xiàn),提高MRI對其診斷和鑒別診斷的準確率.方法:回顧性分析江蘇省寶應縣人民醫(yī)院放射科2013-10/2016-04收治的18例經(jīng)臨床確診或病理證實的SBM患者的MRI資料.結(jié)果:18例SBM中,發(fā)生于幕上14例,幕下4例,位于皮質(zhì)及皮髓質(zhì)交界區(qū)12例,瘤體最大直徑10 mm 4例,10~30 mm 10例,30 mm4例,重度水腫10例,中度水腫3例,輕度水腫2例,無水腫3例,增強后結(jié)節(jié)狀強化3例,環(huán)形強化9例,混合型強化5例,合并出血1例.結(jié)論:SBM的MRI表現(xiàn)多樣,但有一定的特征,瘤體的發(fā)生部位、瘤周水腫程度、MRI平掃和增強形態(tài)等均有助于提高SBM診斷和鑒別診斷的準確率.
[Abstract]:Objective: to investigate the MRI findings of single brain metastases (SBM) and to improve the accuracy of MRI in diagnosis and differential diagnosis. Methods: the MRI data of 18 patients with SBM confirmed by clinical diagnosis or pathology were retrospectively analyzed in radiology department of Baoying County people's Hospital, Jiangsu Province, 2013-10 / 2016-04. Results among 18 cases of SBM, 14 cases occurred in supratentorial area, 4 cases in subtentorial area, 12 cases in the junction of cortex and medulla, 10 cases with 10 30 mm in maximum diameter, 10 cases with severe edema, 10 cases with severe edema, 3 cases with moderate edema and 2 cases with mild edema. No edema was found in 3 cases, nodular enhancement in 3 cases, circular enhancement in 9 cases, mixed enhancement in 5 cases and hemorrhage in 1 case. Conclusion the MRI findings of MRI were various, but had certain characteristics. The location of tumor, the degree of edema around the tumor and the enhanced morphology were all helpful to improve the accuracy of diagnosis and differential diagnosis of SBM.
