Objective To evaluate MRI in the diagnosing of clivus tumors.
目的探讨MRI诊断斜坡肿瘤的价值。
Results (1) 31 cases showed clivus involvement, 6 of which had mass in prepontile cistern.
结果（1）斜坡破坏31例，6例在桥脑前池形成肿块。
Midline vertical compartment is formed with planum sphenoidale, tuberculum sellae and clivus notch.
中线垂直间隔由蝶骨平台、鞍结节、蝶鞍和斜坡切迹组成；
Lesions extending to the upper third of the clivus may be biopsied or partially removed through this approach.
通过此入路可对扩展到斜坡上三分之一的病变行活检或部分切除。
The primary clivus tumor demonstrated expansive growth, while the secondary tumor displayed invasive extension.
原发性肿瘤呈膨胀性生长，继发肿瘤多呈浸润性改变。
The cavernous sinus was the most easily involved structure (29.4%), followed by optic chiasm (21.8%) and clivus (14.1%).
海绵窦是最容易受累的结构（29.4%），其次是视交叉（21.8%）和斜坡（14.1%）。
Conclusion: The nerve must be identified and protected in the operation of clivus, cavernous sinus and lesser sphenoid wing.
结论：在枕骨斜坡区、海绵窦上缘和蝶骨小翼外下方手术时，应特别注意辨认和保护动眼神经。
Potentially any craniopharyngioma at the sellar region may invade into and destroy the underlying sella turcica and clivus (above sphenoid sinus).
任何蝶鞍部的颅咽管瘤都有潜在性的侵袭破坏蝶鞍和筛窦。
Conclusion MRI is able to display size, shape, borderline and signal characteristics of tumors in clivus chordoma, contributing to diagnosis of them.
结论MRI可以准确显示斜坡脊索瘤的大小、形态、边界和信号特点，有利于该病的诊断。
That approach to the clivus is slightly oblique, but can provide as wide an exposure as is achieved with the approaches involving a bilateral maxillotomy.
这种入路到达斜坡的方向稍有倾斜，但是其显露的宽度与双侧上颌骨切开术相比不相上下。
The advantage of this approach is the low complication rate, and the disadvantage is the small operative field limited to the superior third of the clivus.
这一入路的优点是手术并发症较少，缺点是术野小仅限于斜坡的上三分之一。
Relative intensity on early phase of DCE MRI and relative intensity-time curves of clivus, original nasopharyngeal tumor, condylar process, and nasal concha were measured.
测量动态早期斜坡、原发肿瘤、髁突、鼻甲的相对信号强度并作出动态曲线。
In approaching the clivus, the floor of the sella turcica may be removed and the bony opening extended downward on the clivus to the inferior margin of the sphenoid sinus.
为到达斜坡，有可能需要切除鞍底，然后将骨窗向下扩大到斜坡直至蝶窦下缘。
Conclusion: the CT and MRI features of the clivus chordoma are useful for diagnosis, the clivus chordoma must be differentiated from chondrosarcoma, meningioma and nasopharynx tumors.
结论：CT和MRI是诊断斜坡脊索瘤有效的检查方法，斜坡脊索瘤必须与颅底骨软骨肉瘤、斜坡脑膜瘤和鼻咽部肿瘤鉴别。
Result IPS courses in the sulcus for inferior petrosal sinus, that was, on the intracranial surface of the petroclival fissure which was made up of the clivus and the petrous pyramid.
结果IPS行于颅底内面的岩下窦沟内，即由斜坡和颞骨岩部组成的岩斜裂内，形状不规则。
