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。
Yellow tumor like pituitary inflammation clinically rare. A 33-year-old female patient presented with cortical hypofunction due to headache, visual impairment, menopause and laboratory endocrinology examination. Magnetic resonance imaging showed a saddle area occupancy, T1WI was equal signal, T2WI slightly higher signal, enhanced lesion was obvious Homogeneous enhancement, thickening of the pituitary stalk, the optic chiasm is pushed up the shift, the left cavernous sinus invasion, mass around the left internal carotid artery, coronal bit was slightly “triangle ”. Preoperative diagnosis of pituitary adenoma, under general anesthesia in the saddle area and saddle lesions removal surgery + optic nerve decompression, the pathological examination showed microscopic interstitial foam cells, lymphocytes, granulocytes significantly proliferate, support Yellow tumor-like pituitary inflammation. The MRI features of yellow tumor-like pituitary inflammation have certain characteristics. The most typical MRI features are thickening of the pituitary stalk and “triangle” in the MRI coronal position due to the thickening pituitary stalk and the violation of the cavernous sinus. Analysis of its imaging features can help to improve the diagnostic accuracy and select the appropriate treatment.
