摘要：目的：探讨术前MRI检查对垂体腺瘤手术入路选择的运用价值。方法：搜集我院近4年经MRI检查和手术证实的垂体腺瘤患者45例，分析垂体腺瘤的信号特点、生长范围及生长方式。结果：32例肿瘤突破鞍隔向鞍上生长，其中21例视交叉受累；26例向下破坏鞍底进入蝶窦；17例向一侧或两侧侵犯鞍旁和海绵窦，推压或包裹颈内动脉。结论：MRI能明确垂体腺瘤向周围的侵犯范围及生长方式，对其手术入路的选择具有重要价值。

    Abstract： Objective： To explore the value of pro-surgery MRI for the choice of surgical approach to pituitary adenoma. Method： Forty-five cases of pituitary adenoma in our hospital examined by MRI and proved by surgical pathology were collected. Analyzed the tumors’ signal characteristic, extension and growth mode. Result： Among 45 cases of pituitary adenoma,32 cases showed the tumor growing up and breaking through sphenoid partition,21 cases of these oppressing the optic chiasma; 26 cases showed the tumor destroying sphenoid fundus and breaking into sphenoid sinus;17 cases showed the tumor involving one or both sides of the parasellar and cavernous sinus, processing or enwrapping internal carotid artery. Conclusion： MRI can show clearly the area of the involvement of the tumor and growth mode, have great value for the choice of surgical approach to pituitary adenoma. ......
