摘要:
目的 研究侵袭性垂体腺瘤的MRI影像特征。方法 回顾分析32例经手术及病理证实的侵袭性垂体腺瘤的MRI表现。结果 侵袭性垂体腺瘤的MRI影像学表现:①肿瘤超过颈内动脉(ICA)外侧壁切线;②海绵窦外侧静脉丛间隙消失;③3个或3个以上海绵窦静脉丛间隙消失;④窦内颈内动脉(ICA)被包绕50%以上,甚至被完全包裹。结论 MRI以无创伤、无骨伪影、软组织分辨率高、解剖背景清楚及三维成像等优点,是术前诊断侵袭性垂体腺瘤最主要和最重要的检查手段。
Abstract:
Objective To study the value of MRI imaging in the diagnosis of invasive pituitary adenoma. Methods Review and analysis the MRI sign in the 32 patients of invasive pituitary adenoma comfirmed by operation and pathology. Results The following signs have been found to represent accurate criteria for invasive pituitary adenoma:①Adenoma exceeded the lateral intercarotid(ICA) line;②Cavernous sirus lateral venous compartments disappeared;③Occlusion of three or more cavernous sinus venous compartments disappeared; ④Percentage of encasement of the intracavemous ICA higher than 50% was crossed. Conclusions No trauma, no bone shadow, higher soft tissue resolution, clear anatomy background and 3D imaging act as MRI’s virtue, which have became the capital examination means of preoperative diagnosis of infestation vascular tumor.
