| 摘 要： | 目的探讨钙化性砂粒体型脑膜瘤的CT与MRI特征及病理学表现,以提高对其诊断准确性。资料与方法搜集经手术病理证实的钙化性砂粒体型脑膜瘤患者资料7例,男2例,女5例,年龄39～66岁(平均56岁)。行CT检查者3例,增强扫描2例;行MRI检查者6例,均行平扫加增强扫描;同时行MRI与CT检查者2例。结果 7例中,全瘤钙化者2例,厚环状钙化者1例,多发散在点条状钙化者4例。CT平扫肿瘤呈高密度为主的混杂密度,增强扫描高密度区无强化。MRIT1WI呈明显低信号、稍低信号或等信号,T2WI呈低信号、等信号或稍高信号;增强扫描肿瘤明显不均匀强化,低信号区亦有强化,可见脑膜尾征者3例。结论 CT与MRI结合能更全面显示钙化性砂粒体型脑膜瘤的特征,可提高其诊断准确性。

| Abstract: | Objective To present CT, MRI and pathological findings of calcified psammomatous meningioma,so as to improve the diagnosis. Materials and Methods CT and MRI characteristic of 7 patients (2 males and 5 females,39 to 66 years old with the mean age of 56 years) with psammomatous meningioma proved by pathology were analyzed. Three patients underwent CT examination(two underwent enhanced scan),and 6 patients underwent MRI scan. Two patients were examined by both CT and MRI. Results Among 7 calcified psammomatous... |
