| 目的 探讨鼻咽癌的磁共振表现及蔓延和转移规律。方法 回顾性分析180例经病理证实的初诊鼻咽癌患者,观察鼻咽癌及向周围结构侵犯和转移的MRI表现及规律。结果 肿瘤位于侧壁及咽隐窝区共70例,顶后壁48例,侵犯两壁以上62例。对周围结构的侵犯:咽后间隙受侵137例,头长肌受侵97例,咽旁间隙受侵110例,侵及翼腭窝31例,翼内肌83例,翼外肌19例,翼板骨质43例,后鼻孔42例,鼻腔36例,口咽48例,副鼻窦受侵:其中蝶窦30例,筛窦22例,上颌窦11例,岩骨75例,斜坡89例,蝶窦底壁33例,海绵窦受侵28例,卵圆孔 35例,舌下神经管22例,破裂孔57例。淋巴结转移:咽后外侧组淋巴结转移118例,颈上深组淋巴结转移140例。结论 磁共振对显示鼻咽癌的侵犯范围、程度、淋巴结转移及分期有重大价值,是鼻咽癌首选的检查方法。 |

| Objective To evaluate the MRI appearance and the patterns of invasion and metastasis of nasopharyngeal carcinoma. Methods 180 patients with nasopharyngeal carcinoma which were histo-pathologically proved were retrospectively studied. The manifestations of MRI and patterns of nasopharyngeal carcinoma were observed. Results The primary lesions which located at fossa of Rosenmueller and two lateral wall was 70 cases, top-posterior wall 48 cases, extent beyond two walls 62 cases. The invaded structures included retropharyngeal space 137 cases, longus scapitis 97 cases, parapharyngeal space 110 cases, pterygopalatine fossa 31 cases, medial pterygoid muscle 83 cases, lateral pterygoid muscle 19 cases, pterygoid plate 43 cases, posterior of nostril 42 cases, nasal cavity 36 cases, oropharynx 48 cases, sphenoid sinus 30 cases, ethmoid sinus 22 cases, maxillary sinus 11 cases, the destruction of bone of petrous temporal bone 75 cases, and clivus and anterior border of foramen magnum 89 cases, bone of sphenoid sinus floor 33 cases, cavenous sinus 28 cases, foramen ovale 35 cases, and hypoglossal canal 22 cases, foramen lacerum 57 cases. Lymph node metastasis included lateral retropharyngeal lymph nodes 118 cases, neck upper-deep lymph nodes 140 cases. Conclusion MRI has great value in demonstrating the invaded extent and lymph node metastasis. It is the first choice of all examining methods. |
