| 目的 探讨MRI在侵袭性垂体腺瘤中的诊断价值,提高其术前正确诊断率。方法 回顾性分析110例MR诊断并经手术病理结果证实的垂体腺瘤。结果 MRI诊断52例侵袭性垂体腺瘤,表现为突破鞍隔向鞍上生长;侵入蝶窦;累及海绵窦、包绕颈内动脉。术中发现65例为侵袭性生长,MRI阳性预测值为86.5%。侵袭性垂体腺瘤以多功能腺瘤和泌乳素腺瘤多见,分别占33.8%、24.6%。结论 MR诊断侵袭性垂体腺瘤具有较高的敏感性和阳性率,对治疗方案的选择有重要的指导意义。 |

| Objective To assess the value of MRI in diagnosis of invasive pituitary adenomas and to improve the diagnostic accuracy of the disease. Methods One hundred and ten patients with pituitary adenomas verified by pathology were studied. MRI findings were analyzed and compared with the surgical and pathological results. Results Fifty-two patients were diagnosed with invasive pituitary adenomas by MRI. Its findings included: pituitary adenomas through the sellar diaphragm into suprasellar cistern; invasion of sphenoid sinus; involvement of cavernous sinus, encasement of internal carotid artery. Sixty-five patients were found invasion by surgery. The positive predictive value of MRI in the diagnosis of invasive pituitary adenomas was 86.5%. Multifunctional adenoma and prolactin (PRL) secreting adenoma were often found in invasive pituitary adenomas, the percentage were 33.8%, 24.6% respectively. PRL adenomas were more prone to pituitary apoplexy. Conclusion MRI had higher sensitive and positive predictive in diagnosis of invasive pituitary adenomas. It can provide important information for selecting the best treatment strategy. |
