From April 1984 to April 1986, 993 NPC patients were scanned with an 8800 CT scanner in our hospital. 200 consecutive cases who had CT scan before treatment were selected for analysis. CT features of local invasion, incidence of involvement of the parapharyngeal spaces and the adjacent structures, and bone destruction of the base of the skull were analysed. The results showed that the mode of local spread of nasopharyngeal carcinoma is direct infiltration. It tends to spread posterolaterally. According to the relation of the carotid sheath area and lymph nodes in the neck, it is most likely that metastasis in the cervical lymph nodes is the result of direct spread of the disease via the carotid sheath area. CT could detect more bone destruction of the skull base than the conventional submental view. The relationship of neck lymph node metastasis and bone destruction is discussed.
1984年4月至1986年4月，我院用8800型CT扫描仪对993例鼻咽癌患者进行了扫描。选取200例治疗前接受CT扫描的连续病例进行分析。分析了局部侵犯的CT特征、咽旁间隙及相邻结构的受累发生率以及颅底骨质破坏情况。结果显示，鼻咽癌的局部扩散方式为直接浸润。它倾向于向后外侧扩散。根据颈动脉鞘区与颈部淋巴结的关系，颈部淋巴结转移很可能是疾病通过颈动脉鞘区直接扩散的结果。CT比传统的颏下视图能检测到更多的颅底骨质破坏。并对颈部淋巴结转移与骨质破坏的关系进行了讨论。
