Tomographic findings were reviewed in 47 cases of transsphenoidal hypophysectomy for expanding intrasellar mass. Changes caused by factors other than the presence of a mass were classified into five groups. These were: (a) patterns of aeration of the sphenoid sinus, (b) sites of attachment of the sphenoid sinus septum, (c) thickening of the mucous membrane of the sphenoid sinus, (d) extensive thinning of the sellar cortex, and (e) sloping floors. These were the most common sites for causes of error in interpreting expanding lesions. An increased awareness of these pitfalls should decrease interpretive error.
回顾了47例因鞍内肿物扩大而行经蝶窦垂体切除术的病例的断层扫描结果。由肿物以外的因素引起的改变被分为五组。这些因素包括：(a)蝶窦的气化模式，(b)蝶窦间隔的附着部位，(c)蝶窦黏膜增厚，(d)鞍皮质广泛变薄，以及(e)倾斜的鞍底。这些是解释肿物扩大时最常见的错误原因部位。提高对这些陷阱的认识应能减少解释错误。
