【摘要】:目的:探讨单发脑转移瘤(SBM)的磁共振表现,提高MRI对其诊断和鉴别诊断的准确率.方法:回顾性分析江苏省宝应县人民医院放射科2013-10/2016-04收治的18例经临床确诊或病理证实的SBM患者的MRI资料.结果:18例SBM中,发生于幕上14例,幕下4例,位于皮质及皮髓质交界区12例,瘤体最大直径10 mm 4例,10~30 mm 10例,30 mm4例,重度水肿10例,中度水肿3例,轻度水肿2例,无水肿3例,增强后结节状强化3例,环形强化9例,混合型强化5例,合并出血1例.结论:SBM的MRI表现多样,但有一定的特征,瘤体的发生部位、瘤周水肿程度、MRI平扫和增强形态等均有助于提高SBM诊断和鉴别诊断的准确率.
[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.
