目的:探讨鼻咽癌MR脑神经受累的常见部位和诊断标准。方法:回顾性分析23例有脑神经症状的初治鼻咽癌脑神经受累的MR表现和部位。结果:20例海绵窦受累(双侧受累13例),Meckel腔受累8例(双侧受累1例),14例圆孔扩大,20例卵圆孔扩大,10例翼腭窝脂肪间隙消失,12例翼内肌和翼外肌之间脂肪间歇受累,6例眶上裂增宽,11例眶下裂增宽,8例舌下神经孔肿块占位,1例颈静脉孔肿块占位。结论:MR可显示鼻咽癌脑神经受累,有助于准确分期、精确勾画靶区。
Objective: To investigate the common sites and diagnostic criteria of brain involvement in patients with nasopharyngeal carcinoma (MR). Methods: The clinical manifestations and location of 23 patients with craniofacial neoplasm involved in cranial nerve involvement were retrospectively analyzed. RESULTS: Twenty cases of cavernous sinus involvement (bilateral involvement in 13 cases), Meckel cavity involvement in 8 cases (bilateral involvement in one case), 14 cases of circular enlargement, 20 cases of foramen ovale enlargement, 10 cases of pterygopalatine fat gap disappeared, There was intermittent fat involvement in 12 cases between the pterygoid and pterygoid muscles, 6 cases of superior orbital fissure broadened, 11 cases of infraorbital fissure widened, 8 cases of hypoglossal nerve mass and 1 case of jugular foramen mass. Conclusion: MR can show the involvement of cranial nerves in nasopharyngeal carcinoma and help to accurately stage and accurately outline the target.
