目的 探讨脑双侧顶叶多发异常 强化信号的MRI影像学特征。方法 回顾性 分析我院2014年2月-2016年2月期间接收 并治疗的32例具有脑双侧顶叶多发异常强 化特征患者的MRI检查资料，并对患者的 病种类、影像特征等进行综合分析。结果 32例脑双侧顶叶多发异常强化中表现为叶 片状异常强化者15例，结节样异常强化者 9例，弥漫细线样异常强化者6例，结节样 异常强化和细线样异常强化并存者2例。 结论 MRI是检出脑顶叶病变敏感而有效的 方法，不同形态的异常强化的MRI 表现与 不同病因之间有一定关系，对鉴别肿瘤性 具有重要价值, 对某些不同病因的脑顶叶 疾病的诊断和鉴别也可提供进一步的参考 性意见。

Objective To analysis the characteristic of abnormal enhancement MRI imaging of bilateral parietal lobe. Methods Retrospectively analyze of MRI data of 32 patients with abnormal enhancement MRI imaging on bilateral parietal lobe from February 2014 to February 2016, and analysis comprehensively of the disease type and characteristic of MRI image. Results there are 15 cases of blade-like abnormal enhancement, 9 cases of nodular abnormal enhancement, 6 cases of thread-like diffuse abnormal enhancement, 2 cases of combination nodular abnormal enhancement with thread-like diffuse abnormal enhancement. Conclusion MRI is a sensitive and effective method in detection of brain lesions in parietal lobe, different forms of abnormal enhancement of MRI image is relate to the different disease, and have important value in diagnose differentiating tumor. Therefore abnormal enhancement MRI imaging may provide further reference observations on diagnosis and distinguish of different diseases of the brain parietal lobe.
