垂体偶发瘤的研究进展

垂体偶发瘤(Pituitary Incidentalomas)是指因进行尸检或进行与垂体病变无关的头部影像学检查过程中偶然发现的垂体病变,其特点是不具有与垂体疾病相关的临床表现。其尸检发现率约10.7%,影像学检查发现率低于尸检,不同文献报道差异较大。垂体偶发瘤如不进行治疗,10%的偶发微腺瘤和24%的偶发大腺瘤会出现瘤体增大,瘤体增大是明确的手术指征。因此,患者应定期进行头部MRI扫描以明确瘤体有无增大。本文对垂体偶发瘤的相关文献进行回顾分析。

Progress in Pituitary Incidentalomas

Pituitary incidentalomas are almost completely asymptomatic,and therefore usually being detected either at autopsy or as incidental findings on head MRI(or CT) scans performed for other reasons having nothing to do with pituitary gland.The rate about finding pituitary incidentalomas in autopsy is about 10.7%,higher than it in imageology.10 % of microadenomas and 24 % of macroade-nomas will be enlarged if patients with pituitary incidentalomas can not get treatments.Therefore,MRI scans should be performed on these patients to make sure whether there is an enlargement about the tumor which is an specific indication for surgery.This article re-views the the literature about pituitary incidentalomas.
