Abstract
A pleomorphic adenoma in the nasal cavity constitutes a rarity. A 48-year-old woman presented with intranasal pleomorphic adenoma revealed by unilateral continuous obstruction and occasional epistaxis. Nasal endoscopy showed a mucosa-covered and opalescent polypoidal mass arising from the left nasal septum. Unlike cases affecting the major salivary gland, magnetic resonance image (MRI) revealed that the mass showed a low signal intensity on T1-weighted image and a heterogeneous, intermediate signal intensity on T2-weighted image. MRI findings can aid in diagnosis and help exclude the possibility of other neoplasms that occur at this site.
