Abstract:
Choanal polyps belong to a special type of nasal polyps, which are quite uncommon if originating from the nasal septum, especially those with osseous metaplasia. In this article, we report the case of a 63-year-old male patient with persistent nasal obstruction on the right side. An irregular light yellow lobulated mass with smooth surface could be visualized in the nasal cavity through nasal endoscopy, arising from the right nasal septum and extending to the nasopharynx. Computed tomography scan showed a large soft tissue shadow of the nasal meatus, with ossified structure in the center. Histopathological biopsy revealed nasopharyngeal mucositis. The patient underwent functional endoscopic sinus surgery and the polypoidal mass sent for histopathological examination proved to be choanal polyps.
摘要:
鼻息肉属于一种特殊类型的鼻息肉,如果源自鼻中隔,这是很罕见的,尤其是骨化生.在这篇文章中,我们报告一例63岁的男性患者,其右侧持续鼻塞。鼻腔内可见表面光滑的不规则淡黄色分叶状肿块,由右鼻中隔产生并延伸至鼻咽部。计算机断层扫描显示鼻道有一个大的软组织阴影,中心结构僵化。组织病理学活检显示鼻咽部黏膜炎。患者接受了功能性内窥镜鼻窦手术,并送去组织病理学检查的息肉状肿块被证明是后鼻孔息肉。
