松果体区肿瘤的MRI诊断与鉴别诊断
[摘要] 目的 探讨松果体区肿瘤的MRI诊断与鉴别诊断。 方法 回顾分析28例松果体区肿瘤患者MRI诊断资料。 结果 生殖细胞瘤8例，胶质瘤及畸胎瘤各5例，脑膜瘤2例，绒毛膜癌4例，神经母细胞瘤、松果体母细胞瘤、蛛网膜囊肿及皮痒囊肿各1例。诊断结果显示，仅依靠MRI信号难以准确诊断，还需结合临床资料，有助于准确诊断。 结论 MRI检查能够准确显示松果体区肿瘤的形态以及位置，诊断与鉴别诊断可以结合肿瘤的组织学来源确定，有效提高诊断以及鉴别诊断的准确性。

[Abstract] Objective To discuss the MRI diagnosis and differential diagnosis of pineal region tumors. Methods Retrospected and analysed 28 cases of pineal region tumors diagnosed with MRI data. Results 8 cases of germ cell tumor， glioma with teratoma in 5 cases， 2 cases of meningioma， 4 cases of choriocarcinoma， neuroblastoma， pinealoblastoma， arachnoid cyst and skin itching cyst in 1 cases. The diagnostic results showed that only rely on the MRI signal was difficult to accurately diagnose，combined with clinical data was still needed. Conclusion MRI examination could accurately display the pineal region tumor morphology and location， diagnosis and differential diagnosis could be combined with the source to determine the tumor tissue， effectively improved the accuracy diagnosis and differential diagnosis.
