Abstract:
Secondary septal mucocele diagnosed by MRI and CBCT and treated surgically. Objective: Here we report a case of a mucocele of the nasal septum diagnosed by MRI and cone beam CT (CBCT) 23 years after Ogston Luc surgery. Method:A 49-year-old man with nasal obstruction was examined by endoscopy, MRI, and CBCT. Results: Endoscopy showed a smooth and soft septum swelling. MRI revealed an ovalar lesion with high-intensity content on both T1 and T2 images, and a peripheral enhancing rim after i.v. administration of contrast medium. CBCT revealed that the lesion was located in the posterior portion of the septum involving the perpendicular plate of the ethmoid, and destroying the anterior ethmoid cells on the left side but sparing the left lamina papyracea. The patient underwent endoscopic marsupialization of the lesion. Conclusion:A mucocele of the nasal septum is a rare occurrence. MRI and CBCT are effective and affordable diagnostic tools for this condition, enabling differentiation of mucocele from other sinonasal diseases.
