摘要
目的分析侧脑室肿瘤MR表现,探讨其鉴别诊断。资料与方法回顾性分析20例经手术病理证实的侧脑室肿瘤的MRI表现结果20例中,星形细胞瘤6例,脑膜瘤5例,室管膜瘤3例,转移瘤2例,脉络丛乳头状瘤1例,室管膜下巨细胞型星形细胞瘤1例,中枢神经细胞瘤1例,淋巴瘤1例。结果侧脑室肿瘤MRI表现有一定特点,如一般侧脑室脑膜瘤、脉络丛乳头状瘤及淋巴瘤信号较均匀,而星形细胞瘤、室管膜瘤及中枢神经细胞瘤囊变较常见,转移瘤多见坏死,肿瘤的发病部位也有一点特点,如侧脑室脑膜瘤、脉络丛乳头状瘤及室管膜瘤均好发于侧脑室三角区,中枢神经细胞瘤和室管膜下巨细胞星形细胞瘤均好发于室间孔附近,星形细胞瘤及转移瘤可以位于侧脑室任何部位。结论结合肿瘤的部位、发病年龄、强化程度等MR表现可提高诊断的准确率。
Objective To analyze MR findings of lateral ventricle tumors,discuss its differential diagnosis.Materials and methods A retrospective analysis of 20 cases confirmed by operation and pathology of the lateral ventricle tumors MRI performance results in 20 cases,astrocytoma in 6 cases,5 cases of meningioma,ependymoma in 3 cases,2 cases of metastatic tumor,choroid plexus papilloma in 1 cases,subependymal giant cell astrocytoma in 1 cases,1 cases of central neurocytoma with,lymphoma a report of 1 cases.Results The results of lateral ventricle tumors MRI have certain characteristics,such as general,lateral ventricle choroid plexus papilloma and lymphoma signal is more uniform,and astrocytoma,ependymoma and central neurcytoma with cystic lesions are more common,metastases seen necrosis,tumor sites also have a characteristic,such as side intraventricular meningioma,choroid plexus papillomas and ependymomas have occurred in the trigone of lateral ventricles,central neurocytoma and subependymal giant cell astrocytoma have occurred in the vicinity of the interventricular foramen,astrocytic tumors and metastases can be located in any part of the lateral ventricle.Conclusion the tumor site,age of onset,degree of enhancement and MR findings may improve the diagnostic accuracy rate.
