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.

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.

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