摘　　要：目的　探讨鼻咽癌浸润性蔓延的 CT表现 ,着重研究颅底骨受侵的部位、范围、形态的 CT表现。方法　对 6 8例鼻咽癌浸润性蔓延的 CT图像和临床资料作回顾性分析 ,其中男性 5 0例 ,女性 18例 ,全部病例均经病理证实。 CT扫描以听眦线 (OML )为基线向上平行扫描至颅底 ,向下扫描至鼻咽及颈部。结果　鼻咽癌病人继发头痛和颅神经损害症状是颅底骨破坏的首发症状 ,占 6 8.3%。肿瘤多发生于顶壁和后壁 ,占 70 %。颅底骨破坏包括溶骨性破坏 (48.2 % ) ,硬化性改变 (10 .4 % )和混合性破坏 (41.4 % )。结论　颅底骨破坏是鼻咽癌向上浸润蔓延的主要表现 ,CT对判断鼻咽癌向上蔓延的范围及表现和显示颅底各部位结构有重要价值。Objective To study CT features of nasopharngeal carcinoma(NPC) with infiltrative pervasion and emphasize the research for location,range,pattern and CT demonstrating the skull base erosion.Methods Sixty eight cases with CT images and clinical data of NPC with infiltrative pervasion were retrospectively studied(50 males,18 females).All cases were confirmed by pathology.With OML as baseline,scanning the skull base cephalad,scanning the nasopharynx and cervix caudad.Results The first place in clinical symptoms of NPC with infiltrative pervasion was headache(68.3%);primary lesions were in roof posterior wall of nasopharynx(70%).CT demonstrated skull base erosions included osteolytic lesion(48.2%),bone sclerosis (10.4%) and mixed destruction(41.4%).Conclusion The skull base destruction is the main manifestation of NPC with up spread.CT has considerable value for detecting the range and manifestation of NPC with up spread.
