摘要
目的:探讨鼻咽癌侵犯海绵窦的CT特点。材料与方法:搜集病理确诊的鼻咽癌伴有前组颅神经损害为主要临床症状的CT资料25例。使用GE Lightspeed GX/i双层螺旋CT;18例进行CT增强扫描。结果:(1)两侧海绵窦不对称侵犯,左12例,右9例,双侧4例;(2)受累海绵窦呈局限或弥漫性增厚17例;(3)颈内动脉受累8例,颅神经受累21例,视神经受累3例;(4)海绵窦异常强化17例,脑膜异常强化3例;(5)骨质破坏:蝶窦7例,筛窦3例,颅底17例。结论:CT可精确显示鼻咽癌侵犯海绵窦的部位、途径、范围和程度,是优良的诊断方法。
Purpose: To study CT features of the cavernous sinus invaded by nasophamgeal carcinoma (NPC). Materials and Methods: 25 cases of CT in NPC with frontal group cranial nerve damaged proved by pathology were reviewed retrospectively. With GE lightspeed GX/ I Dual- phase helical CT. Results: (1) Asymmetry of bilateral ca vemous sinus, left side 12 cases, right side 9 cases, and bilateral 4 cases; (2) Local ogr diffuse thickend of ca vernous sinus 17 cases; (3) Displacemment or encasement of artery (8 cases) and cranial nerve (21 eases), and optic nerve dioplasement 3 cases; (4) Abnormal enhancement of cavernous sinus 15 cases and dural meningeal 3 cases; (5) Destruction of bone: sphenoid sinus 7 cases, ethomoid sinus 3 cases, base of skull 17 cases. Conclusion: CT could provide accurate .assessment the location, passage, extent of the cavernous sinus invaded by NPC.
