Abstract

Mucoceles are relatively common cystic lesions of the paranasal sinuses. However, mucocele of the nasal septum is extremely rare. We report a case of a mucocele present in this unusual location. Mucocele of the nasal septum should be considered in the differential diagnosis of a mass of the nasal septum and/or median canthal region. Nasal septal mucocele can be effectively treated with endoscopic marsupialization or complete excision.

  Fig. 1. Endoscopic examination shows a submucosal mass (as-terisk) on the left nasal septum (S).

• 

  Fig. 2. Enhanced CT of the paranasal sinuses (A) revealed a 1.5 cm sized high attenuated cystic mass (arrow) in the left nasal septum. On MRI, a mass (arrow) on the left nasal septum had high signal on T1-weighted image (B) and low signal on T2-weighted image (C), suggesting a mucocele.

  Fig. 3. (A) Intraoperative appearance of left nasal cavity following endoscopic marsupialization (B) At 3months’ follow up, endoscopic examination shows a well marsupialized cavity on the left nasal septum.

  Fig. 4. Histopatholgoic examination shows that a cyst is lined by low cuboidal epithelium and little inflammatory cells (Hematoxylin & Eosin staining, ×200).
