摘要
目的：探讨鼻咽癌侵犯海绵窦的ＣＴ特点。材料与方法：搜集经病理确诊为鼻咽癌并伴有海绵窦占位３６例，行鼻咽及海绵窦ＣＴ检查。３４例轴位扫描，层厚及层间距均为５ｍｍ；２例冠扫，层厚和层间距均为３ｍｍ。其中１２例行增强扫描。结果：（１）鼻咽癌原发病灶３６例；（２）海绵窦不对称３６例。患侧呈局限性、弧状或弥漫性增宽，增宽幅度为０．６～２ｃｍ，平均１．２ｃｍ；（３）颅底骨质破坏３１例，其中以破裂孔和卵圆孔的破坏或吸收扩大为最常见，分别为３０例和２３例。５例骨质未见明确改变。结论：ＣＴ可明确显示鼻咽癌侵犯海绵窦的部位、途径及范围，有助于临床分期及预后的判断，是一种优良的检查方法。
Purpose:To analyze CT imaging features of nasopharyngeal carcinoma (NPC) with cavernous sinus involvement. Materials and Methods:The CT findings in 36 cases of NPC with cavernous sinus involvement proved by biopsy were reviewed retrospectively. CT scanning was Performed in all patients, using 5mm axial scans with 5mm spacing in 34 cases and 3mm coronal scans with 3mm spacing in 2 case, and 11 cases were enhanced with Angiografin. Result: (1 )There were primary lesions of NPC in 36 cases and asymmetry of bilateral cavernous sinuses in 36 cases. The side of involvement became wider and the width extent was 0. 6-2cm, mean 1.2cm; There were destruction of the base bone in 31 cases. The most common place was the destruction or dilation of the foramen lacerum and the foramen ovale, which was 30 cases and 23 cases respectively. Conclusion: CT can present the accurate location, spread direction and extent of the cavernous sinuses invaded by NPC, and it is helpful for T-staging and evaluating prognosis.
