【摘要】：黄色瘤样垂体炎临床上极少见。1例33岁女性患者,因头痛、视力障碍、停经入院,实验室内分泌学检查提示皮质功能减退;MRI检查表现为鞍区占位,T1WI呈等信号,T2WI为略高信号,增强后病变明显均匀强化,垂体柄增粗,视交叉被向上推压移位,左侧海绵窦受侵,肿块包绕左侧颈内动脉,冠状位上略呈"三角形"。术前诊断为垂体腺瘤,在全身麻醉下行鞍区及鞍上占位病变切除术+视神经减压术,病理检查表现为镜下见间质泡沫细胞、淋巴浆细胞、粒细胞明显增生,支持黄色瘤样垂体炎。黄色瘤样垂体炎的MRI表现有一定的特征性,其最典型的MRI特点是垂体柄增粗及由于增粗的垂体柄、侵犯海绵窦而在MRI冠状位上表现为"三角形"。分析其影像学特点有助于提高诊断的准确性及选择适宜的治疗方案。
[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.
