咽旁间隙肿瘤的影像学诊断

目的：通过对咽旁间隙肿瘤CT、MRI检查资料的分析研究，探讨影像学检查在咽旁间隙肿瘤诊断中的意义。方法：收集1988年1月～2005年1月我科收治的咽旁间隙肿瘤患者138例，咽旁间隙的转移性肿瘤和侵及咽旁间隙的鼻咽癌未计人内。所有病例均作CT或（和）MRI检查。结果：CT和MRI可较好地提供肿瘤的位置、大小、范围、肿瘤的边缘是否光滑及与颈部大血管的关系，为制订手术方案提供重要的参考意见。结论：术前行CT、MRI检查对咽旁间隙肿瘤治疗方案和手术径路的选择有重要意义。

Imaging diagnosis of tumor in parapharyngeal space

Objective:To investigate the diagnostic value of CT and MRI in tumors of parapharyngeal space(PPS).Method:The data of one hundred and thirty-eight patients with PPS tumor treated in our department during the period from January, 1988 to January, 2005 were collected and reviewed. Eighty-three men and 55 women were enrolled, not including patients with metastasis tumors in PPS or nasopharyngeal carcinomas invading PPS.The age varies from 7 to 73 yrs(average 44.7 yrs). Among the patients, 12 were operated for the second time because of recurrence. All the patients were examined by CT or/and MRI.Result:CT and MRI could provide the position, size, confine of the tumor and its relationship with cervical blood vessels well, which were important to operation schemes.Conclusion:CT and MRI before operation are valuable to the treatment of PPS tumors.
