摘　　要：目的:分析鼻咽癌鼻咽后部筋膜间隙受累的影像学表现,探讨椎前肌侵犯与颅底枕骨侵犯的相关性。方法:搜集行鼻咽及颈部MRI检查且未经治疗的新发鼻咽癌患者152例,总结其病变周围组织结构侵犯的规律,并结合文献分析鼻咽癌鼻咽后部筋膜间隙受累的相关性。结果:鼻咽癌鼻咽周围组织结构侵犯以椎前肌(62.50%,95/152)最常见,其次为咽旁间隙(52.63%,80/152)、颅底枕骨(36.84%,56/152)、翼内肌(30.92%,47/152)、海绵窦(14.47%,22/152)、翼外肌(9.87%,15/152)。经Spearman相关性分析,鼻咽癌咽后淋巴结转移与椎前肌侵犯rs=-0.088,P=0.283,两者无相关性;鼻咽癌椎前肌侵犯与颅底枕骨侵犯rs=0.507,P<0.001,两者存在相关性。结论:鼻咽癌椎前肌及颅底枕骨具有高侵犯率并存在相关性;两者受侵对预后是否具有相似的临床意义需进一步研究。Objective:To analyze the imaging features of the nasopharyngeal tissue and posterior nasopharyngeal fascial space involvement in nasopharyngeal carcinoma,and to explore the correlation between prevertebral muscle invasion and occipital skull base invasion.Methods:A group of 152 untreated patients with nasopharyngeal carcinoma who underwent MRI of the nasopharynx and neck were enrolled,and the tissue structure invasion around lesions was summarized.The characteristics and correlation of invasion of the fascial space in the posterior nasopharynx of the nasopharyngeal carcinoma were analyzed by combining with the literature.Results:The most common tissue invaded by nasopharyngeal carcinoma was the prevertebral muscle(62.50%),followed by parapharyngeal space(52.63%)and the occipital skull base(36.84%),internal pterygoid muscle(30.92%),cavernous sinus(14.47%),and lateral pterygoid muscle(9.87%).Spearman rank correlation coefficient between the retropharyngeal lymph node metastasis and invasion of prevertebral muscle in nasopharyngeal carcinoma was-0.088(P=0.283),which indicated no significant correlation.Spearman rank correlation coefficient between the invasion of prevertebral muscle and occipital skull base invasion in nasopharyngeal carcinoma patients was 0.507(P<0.001),which indicated a significant correlation.Conclusions:Prevertebral muscle and occipital skull base invasion have a high invasion rate and significant correlation in nasopharyngeal carcinoma,and whether this has similar clinical significance for nasopharyngeal carcinoma prognosis needs further study.
