摘要
目的通过分析垂体腺瘤患者的MRI-T1WI图像, 探讨垂体后叶亮点(PPBS)的出现率、位置分布及其影响因素。方法选择南京军区福州总医院神经外科自2012年9月至2014年9月收治的垂体腺瘤患者123例, 所有患者术前行MRI SE序列的T1WI、T2WI矢状位、冠状位、轴位平扫和增强扫描。观察垂体腺瘤的形态、PPBS的位置与信号, 比较不同形态垂体腺瘤患者的PPBS以及出现PPBS与未出现PPBS垂体腺瘤患者的临床资料。结果本组患者中出现PPBS者98例(79.7%), 未出现PPBS者25例(20.3%);垂体腺瘤中沙漏型43例、筒型63例、楔型17例;统计结果显示沙漏型垂体腺瘤患者PPBS出现率较筒型高, 筒型和楔型垂体腺瘤患者PPBS与脑桥的信号强度比较沙漏型高, 差异有统计学意义(P<0.05);未出现PPBS组垂体腺瘤患者肿瘤高度、体积均大于出现PPBS组, 差异有统计学意义(P<0.05)。出现PPBS与未出现PPBS垂体腺瘤患者的腺瘤形态分布不同, 差异有统计学意义(P<0.05)。结论 MRI图像能够较好地显示PPBS, 且PPBS的出现与垂体腺瘤的形态、体积、高度有关。
