摘要
目的:进一步探索以颅神经麻痹(CNP)以及用CT和MRI诊断鼻咽癌局部复发(NPCLR)的方法。方法:选取100例超腔的NPCLR病人仔细研究其CNP的规律,及其CT和/或MRI的表现。结果:70%的NPCLR病人有CNP,主要侵犯外展神经(51.4%)和三叉神经(67.1%)。与此相反,颅神经放射损伤,则最多侵及舌下神经(67.4%)。在本组病人的CT和/或MRI片上均可见鼻咽以外的深部解剖结构受累的现象,其中最常受累者为颅底骨(58%),其次为海绵窦(25%),翼腭窝(21%),脑桥小脑角(16%),咽旁(14%)和鼻腔(12%),咽后淋巴结复发亦不少(22%)。结论:NPC放疗后出现CNP固然可以高度怀疑其局部复发,但最后诊断尚须根据CT,尤其MRI检查。
Objective:To explore further the cranial never palsy and CT, MRI for diagnosis of local recurrence of nasopharyngeal carinoma (NPCLR).Methods:By reviewing all available materials of 100 patients with confirmed NPCLR beyond the incolvemenr of nasopharynx.Results:Seventy patients had cranial nerve palysy mainly involved the abducent nerve (51.4%) and the trigeminal nerve (67.1%),in contrast to radiation induced injury which invdved mostly the sublingual nerve (67.4%).CT and MRI showed abnormal ities ities in deep structures which were as follows:base of skull (48%),cavernous sinus (25%),pterygopalatine fossa (21%),cerebellopontine angle (16%),parapharyngeal space (14%),nasal cavity (12%),and the Rouviere's nodes (22%).Conclusion:In view of development of cranial nerve palsy in patient after irradiation for NPC,NPCLR may be suspected,but the final diagnosis must be based upon CT and in particodar,the MRI findings.
