目的探讨鼻腔鼻窦内翻性乳头状瘤起源的CT影像学特点。方法回顾性分析47例经鼻内镜手术及术后病理组织学确诊的鼻腔鼻窦内翻性乳头状瘤患者的CT影像学资料。对肿瘤病变在CT上的骨质变化进行分析,并与术中发现的肿瘤起源根蒂部位进行对比,分析CT影像中骨质改变与肿瘤起源之间的关系。结果 47例患者中,39例有骨质增生影像表现,其中37例骨质增生部位与肿瘤起源的根蒂部位一致,一致性达78.7%,提示可根据骨质增生部位推测肿瘤起源位置。结论 CT影像中的骨质增生与鼻腔鼻窦内翻性乳头状瘤的根蒂起源部位有较高的一致性,有助于术前评估肿瘤起源和指导术前制定合理的手术方案。
Objective To investigate the CT imaging features of the origin of inverted papilloma in nasal sinuses. Methods A retrospective analysis of 47 cases of endoscopic sinus surgery and histopathological diagnosis of nasal sinus inverted papilloma patients CT imaging data. The changes of bone lesions on CT were analyzed and compared with those found in the operation. The relationship between the bone changes and the tumor origin in CT images was analyzed. Results Of the 47 patients, 39 had osteoarthroplasty. Among them, 37 had osteoarthropathy sites which were consistent with the origin of tumors, and their concordance reached 78.7%, suggesting that the location of tumor could be estimated according to the site of osteoarthropathy. Conclusions The hyperosteogeny in CT images is in good agreement with the origin of rhinotracheal inverted papilloma. It is helpful to evaluate the origin of the tumor preoperatively and guide the rational operation of the procedure.
