目的:探讨成人鼻咽喉部鳞状上皮乳头状瘤的CT表现,提高诊断的准确性。方法:回顾性分析经内镜及手术病理检查证实的24例成人鼻咽喉部鳞状上皮乳头状瘤患者的临床及CT影像学资料,总结病变部位、形态、增强及与邻近组织的关系等特征。结果:成人鼻咽喉部鳞状上皮乳头状瘤CT主要表现为黏膜弥漫均匀增厚肿胀,部分可形成结节或肿块,临近腔隙变窄,周围脂肪间隙存在,增强扫描呈均匀性轻中度渐进性强化(强化CT值20~45HU),若恶变则动脉期明显强化(强化CT值>45HU)或不均匀强化。结论:成人鼻咽喉部鳞状上皮乳头状瘤的CT表现具有一定特征,可为临床提供更多诊断信息。
Objective: To investigate the CT findings of adult nasopharyngeal and laryngeal squamous cell papilloma and to improve the diagnostic accuracy. Methods: The clinical and CT imaging data of 24 cases of nasopharyngeal squamous epithelial papilloma confirmed by endoscopy and surgical pathology were retrospectively analyzed. The features, such as lesion location, morphology, enhancement and the relationship with adjacent tissues were summarized . Results: CT in adult nasopharyngeal laryngeal squamous cell papilloma mainly manifested as thickening and swelling of the mucosa diffusely and uniformly, nodules or lumps in some of the nodules, narrowing adjacent to the lacunar cavity, presence of surrounding fat interstitial space, Progressive enhancement (enhanced CT value 20 ~ 45HU), if the malignant change was significantly enhanced arterial phase (enhanced CT value> 45HU) or uneven enhancement. Conclusion: CT features of adult nasopharyngeal and laryngeal squamous cell papilloma have certain characteristics, which can provide more diagnostic information for clinic.
