目的探讨垂体转移瘤的磁共振成像特征.方法回顾性分析9例经病理或临床随访证实的垂体转移瘤的磁共振影像资料,寻找其特征性表现.结果 MR影像均显示转移瘤位于垂体后叶或垂体柄,呈浸润性生长,T 1 WI多呈低信号,T 2 WI多呈略高信号,其内信号不均匀.增强检查病灶呈明显不均匀强化.结论 MRI对诊断垂体转移瘤有特征性,对垂体转移瘤的诊断及鉴别诊断有重要的参考价值.

Objective To investigate the MRI features of pituitary metastasis. Methods The MR manifestation of 9 cases of pituitary metastasis proven by pathological check and confirmed by following-up observation was analyzed retrospectively. The distribution and extent of lesion was assessed. Results MRI displayed that pituitary metastases were located in the posterior lobe or pituitary stalk and showed infiltrative growth patterns. T 1 WI signal exhibited hypointensity signals and T 2 WI presented hyperdensity signals. The signals were inhomogeneous . And the enhanced scanned lesions had moderate and apparent inhomogenous enhancement. Conclusion The MRI imaging of pituitary metastases had certain features. MRI had important values for the diagnosis and differentiation diagnosis of pituitary metastases.
