We compared MRI studies of the sellar area and embryological and adult histological studies of the cavernous sinuses and pituitary fossa. MRI studies were performed in 50 normal subjects with coronal sections using a fast inversion-recovery sequence to demonstrate the dural walls of the cavernous sinus and pituitary fossa. With this sequence, dura mater appears as a high-signal linear structure. The lateral and superior walls of the cavernous sinus was easily identified on all studies, but demonstration of a dural wall separating the cavernous sinus from the pituitary fossa was not possible. These results correlated well with embryological and adult histological studies obtained from 14 specimens. The absence of a strong separation between the pituitary fossa and the cavernous sinus explains the high incidence of extension of pituitary tumours to the cavernous sinuses and vice versa.
我们比较了蝶鞍区的磁共振成像（MRI）研究以及海绵窦和垂体窝的胚胎学与成人组织学研究。对50名正常受试者进行了MRI研究，采用快速反转恢复序列进行冠状位扫描，以显示海绵窦和垂体窝的硬脑膜壁。在此序列下，硬脑膜呈现为高信号线性结构。在所有研究中，海绵窦的外侧壁和上壁都很容易识别，但无法显示将海绵窦与垂体窝分隔开的硬脑膜壁。这些结果与从14个标本获得的胚胎学和成人组织学研究结果高度相关。垂体窝和海绵窦之间缺乏明显分隔，这解释了垂体肿瘤向海绵窦扩展以及反之亦然的高发生率。
