1·Objective To summarize the features of myxedema coma complicated with operations on the sella tumors, and discuss the preoperative prevention and clinic treatment.
目的探讨鞍区肿瘤术后并发急性黏液水肿性昏迷的特点，提出术前预防及昏迷抢救治疗方案。
2·All cases sustained large pituitary adenoma, and some accompanied with empty sella.
影像学检查均为垂体大腺瘤，部分病人伴有部分空泡蝶鞍。
3·Recently, CT scan is used more often, demonstrating a tow-density area within the sella.
近来常采用脑CT扫描，显示一蝶鞍内低密度的蛛网膜疝囊影，可有助鉴别。
4·This head CT scan demonstrates a mass with irregular margins in the region of the sella. Such a mass may impinge upon the optic chiasm, just like a pituitary adenoma.
头颅CT显示颅咽管瘤，在蝶鞍可见边缘不规则的大肿块，象垂体腺瘤一样压迫视交叉。
5·Macroadenomas due to their larger size grow out of the sella and thus usually demonstrate a waist at the diaphragm sella.
垂体大腺瘤因为较大的体积而向外生长，在鞍隔处显示一个掐腰状改变。
