作者分析１８例经手术病理证实的咽旁间隙肿瘤的ＣＴ所见。将咽旁间隙分为茎突前间隙和茎突后间隙，根据解剖部位各异，其肿瘤的组织发生也不同，就该区域的解剖及病变所在表现，认为咽旁脂肪组织、血管、茎突的移位，变形和增强ＣＴ，对判定肿瘤的组织来源很有帮助。 The authors analyzed 18 cases of pathologically confirmed parapharyngeal space tumor CT seen. The parapharyngeal space is divided into the anterior styloid process and posterior styloid gap, according to anatomical differences, the tumor tissue is also different, the anatomy and lesions in the region where the performance that the parapharyngeal adipose tissue, blood vessels, styloid process Of the shift, deformation and enhanced CT, to determine the source of the organization of the tumor helpful.
