摘要
目的 :研究脑内环形强化转移瘤的MRI表现 ,并探讨其临床诊断价值。方法 :搜集经MRI诊断及手术病理证实的脑内环形强化转移瘤 3 5例 ,男 2 5例 ,女 10例 ,年龄 2 1～ 76岁。所有病例均行MR平扫及增强扫描。结果 :3 5例增强后均有不同程度的强化。脑内环形强化转移瘤可出现壁结节和环壁脐样凹陷。结论 :转移瘤的部位、形态、强化程度对诊断有一定价值。MRI是诊断脑转移瘤的可靠方法 ,MRI增强扫描对脑内环形强化转移瘤的诊断具有重要价值。
Objectoive:To study MR findings of intracranial metastasis with circular enhancement and their value in diagnosis.Methods:35 cases of intracranial metastasis with circular enhancement underwent MRI and proved by pathology.There were 25 male and 10 female,age range 21～76 years.Plain MR scan and enhanced MR scan were performed in all cases.Results:Different degree enhancement was showed on enhanced MRI in all cases.The location,shape and degree of enhancement had certain value for making the diagnosis.Nodule and indentation was occasionally seen in the circular enhancement of metastasis.Conclusion:MRI is a good method for diagnosing cerebral metastasis.Enhanced MRI has a great value.
