摘要
目的探讨脑室内及侵入脑室内肿瘤的定位、定性及它们间的鉴别诊断。方法43例均行横、冠、矢三维的MR平扫及增强扫描,并回顾性分析肿瘤的MR征象。结果43例肿瘤,9类病种,其中室管膜瘤10例,髓母细胞瘤6例,脑膜瘤8例,星形细胞瘤8例,少支胶质瘤3例,脉络丛乳头状瘤、中央性神经细胞瘤、海绵状血管瘤和胶样囊肿各2例。误诊原因主要是肿瘤发生的位置不典型和肿瘤MR征象不典型。结论注意观察脑室内、外的MR定位征象和加强对少见征象的认识,有助于提高诊断。
Objective To explored the localization and definition of intraventricular and invaded ventricular tumors and their diagnosis and differential diagnosis were study in the same way. Methods All 43 cases were performed by MR plain and enhanced scan in transverse, coronal, and sagittal, and Their findings of MRI were analyzed retrospectively. Results There were 9 kind of tumors in 43 cases, inclusive 10 cases were ependymomas, 6 cases were medulloblastomas, 8 cases were meningiomas, 8 cases were astrocytomas, 3 cases were oligodendrogliomas, and 2 cases were choroid plexus papillomas, central neurocytomas, cavernomas and colloid cysts in each one. Mistaken reason were mainly the untypical localization and the untypical signs of the tumors. Conclusion Careful observing of MR findings of the intraventricular and invaded ventricular tumors and understanding the uncommon appearances of tumors in MR can improve the diagnose.
