【摘要】：正患者男,71岁。以"无明显诱因头晕半年,双眼视物模糊且进行性加重3个月"就诊。患者神志清,病理反射阴性。MR检查:蝶鞍扩大,垂体窝内见T1WI、T2WI等信号肿块,垂体柄明显增粗,最大径约1.51cm×0.68cm,矢状位病灶呈葫芦形,与正常腺垂体分界不清,视交叉受压上抬(图1);动态增强早期肿块明显强化,内可见小圆形相对弱强化区,随时间延迟,肿块持续强化,其内相对弱强化区范围缩小至消失(图2、3)。MRI初
[Abstract]:The patient is 71 years old. "dizziness without obvious inducement for half a year, blurry binocular vision and progressive aggravation for 3 months". The sagittal lesions were hyacinth shaped, not distinct from the normal pituitary gland, and T1WIN T2WI signal masses were seen in the pituitary fossa, and the pituitary stalk was obviously thickened, the maximum diameter was about 1.51cm 脳 0.68 cm, the sagittal lesion was hyacinth shape and could not be distinguished from the normal pituitary gland. The optic chiasma was elevated under pressure (Fig. 1); the mass was obviously enhanced in the early stage of dynamic contrast enhancement, and the small circular relatively weak enhancement area could be seen in the early stage. With the delay of time, the enhancement of the mass continued, and the range of the relatively weak enhancement area within the mass was reduced to disappear (fig. 2 / 3).
