摘　　要：目的：探讨鼻咽癌上行性蔓延的ＣＴ表现，着重研究颅底骨受侵的部位、范围、形态的ＣＴ表现。材料与方法：对１３６例鼻咽癌上行性蔓延的ＣＴ图像和临床资料作回顾性分析，其中男性１０６例．女性３０例。全部病例均经病理证实。ＣＴ扫描以 ＯＭＬ为基线向上扫描至颅底，向下扫描包括鼻咽及颈部。结果：鼻咽癌上行性蔓延的首发症状为头痛．占 ６６． ２％．发生于顶后壁的肿瘤最多见，占７２．１％。颅底骨破坏包括溶骨性破坏（４４．９％），硬化性改变（１３．２％）和混合性破坏（４１． ９％）。结论：颅底骨破坏是鼻咽癌上行性蔓延的主要表现， ＣＴ 对判断鼻咽癌上行性蔓延的范围及表现有重要价值。Purpose: To study CT features of nasopharygeal carcinoma (NPC) with up spread, and emphasis research for place, range, parttern and CT demonstrate with base of the skull erosion. Materials and Methods: 136 Cases with CT images and clinical datas of NPC with up spread were retrospective studied (106 males, 30 females). All cases were confirmed by pathology. OML. as baseline of CT scan, include cephalad for skull base, and caudad for nasopharynx and cervical. Results: The first place in clinical symptom of NPC with up spread was headache (66. 2 % ), and primary lesion were roof - posterior wall of nasopharynx (72. 1 % ). CT demonstration with skull base erosion divided into osteolytic lesion (44. 9 % ), sclerosis ossium (13. 2 % ) and mixed destruction (41. 9% ). Conclusion: Base of the skull destruction is main manifestation of NPC with up spread. CT has considerable value for detection of range and manifestation of NPC with up spread.
