【摘要】 目的:探讨术前MR I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MR I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:MR I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。更多还原

【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.更多还原
