Epiphora is the first symptom of acquired nasolacrimal duct obstruction (NLDO), which may be due to various causes, including paranasal sinuses and tumours of the nasal cavity. A 28-year-old male patient presented chronic dacryocystitis with left-sided epiphora. Endoscopically, a bulging of the lateral nasal wall at the left-sided agger nasi area was noted. Imaging studies (CT and MRI) revealed a left-sided giant agger nasi mucocele. An endonasal endoscopic dacryocystorhinostomy (DCR) as well as opening of the agger nasi cell with mucocele removal and anterior ethmoidectomy was performed. Based on the literature, intranasal causes have very often occurred in patients with chronic dacryocystitis, but not reported as the cause of inflammation in the mucocele of agger nasi. Identification and recognition of this endonasal rare cause of NLDO-like agger nasi mucocele entity may facilitate timely intervention and can be treated successfully with a simultaneous endoscopic DCR procedure.
溢泪是获得性鼻泪管阻塞（NLDO）的第一个症状，其可能由多种原因引起，包括鼻窦和鼻腔肿瘤。一名 28 岁男性患者因左侧溢泪出现慢性泪囊炎。内镜检查发现左侧鼻丘区外侧鼻壁隆起。影像学研究（CT 和 MRI）显示左侧巨大鼻丘黏液囊肿。行鼻内内镜下泪囊鼻腔吻合术（DCR）以及开放黏液囊肿和前筛窦切除术。根据文献，慢性泪囊炎患者中鼻腔内原因非常常见，但未报道为鼻丘黏液囊肿炎症的原因。识别和认识这种鼻腔内 NLDO 样鼻丘黏液囊肿实体的罕见原因可能有助于及时干预，并可通过同时进行的内镜 DCR 手术成功治疗。
