【摘要】：黃色瘤樣垂體炎臨床上極少見。1例33歲女性患者,因頭痛、視力障礙、停經(jīng)入院,實(shí)驗(yàn)室內(nèi)分泌學(xué)檢查提示皮質(zhì)功能減退;MRI檢查表現(xiàn)為鞍區(qū)占位,T1WI呈等信號(hào),T2WI為略高信號(hào),增強(qiáng)后病變明顯均勻強(qiáng)化,垂體柄增粗,視交叉被向上推壓移位,左側(cè)海綿竇受侵,腫塊包繞左側(cè)頸內(nèi)動(dòng)脈,冠狀位上略呈"三角形"。術(shù)前診斷為垂體腺瘤,在全身麻醉下行鞍區(qū)及鞍上占位病變切除術(shù)+視神經(jīng)減壓術(shù),病理檢查表現(xiàn)為鏡下見間質(zhì)泡沫細(xì)胞、淋巴漿細(xì)胞、粒細(xì)胞明顯增生,支持黃色瘤樣垂體炎。黃色瘤樣垂體炎的MRI表現(xiàn)有一定的特征性,其最典型的MRI特點(diǎn)是垂體柄增粗及由于增粗的垂體柄、侵犯海綿竇而在MRI冠狀位上表現(xiàn)為"三角形"。分析其影像學(xué)特點(diǎn)有助于提高診斷的準(zhǔn)確性及選擇適宜的治療方案。
[Abstract]:The clinical manifestations of xanthomatous pituitary adenositis were rarely seen in 1 cases of 33 years old female patients with postmenopausal hospitalization due to headache and visual impairment. Laboratory endocrinology showed that the MRI findings of hypocortical dysfunction showed that the Sellar area occupied the Sellar area on T1WI and showed a slight hyperintense signal on T2WI.After enhancement, the lesions were enhanced uniformly, the pituitary stalk was thickened, the optic chiasma was pushed upward and displaced, the left cavernous sinus was invaded, the mass was wrapped around the left internal carotid artery, and the coronal position was slightly "triangular".Before operation, pituitary adenoma was diagnosed. The optic nerve decompression was performed in the Sellar area and suprasellar space occupying lesion under general anesthesia. The pathological examination showed that the interstitial foam cells, lymphoplasmacytes and granulocytes proliferated obviously under microscope.Supporting xanthomatous pituitary adenositis.The MRI features of xanthomatous pituitary adenositis were characterized by the thickening of the pituitary stalk and the "triangle" in the MRI coronal position due to the enlargement of the pituitary stalk and invasion of the cavernous sinus.Analysis of its imaging features will help to improve the accuracy of diagnosis and selection of appropriate treatment.
