Osteomas are common benign tumors of the paranasal sinuses, but are usually asymptomatic and found as a coincidental finding during routine radiological investigations. The aim is to demonstrate typical radiological findings of osteomas and demonstrate rare occurrence of osteoma in middle turbinate.

Patient presenting with recurrent headaches, left-sided facial pain, and intermittent nasal obstruction was evaluated using Philips Brilliance 40-multislice computed tomography scanner, which showed bilateral maxillary and ethmoid sinusitis with bilateral fluid-filled concha bullosa with left-sided concha bullosa showing a well-defined lesion of bone attenuation suggestive of osteoma.

Osteomas can rarely occur in nasal turbinates and may be symptomatic requiring endoscopic/surgical removal.

Radiological investigations are diagnostic for osteomas and play an important role in preoperative planning. Osteomas arising from the turbinates are more easily accessible by endoscopy than sinus osteomas; hence, removal carries less risk. Therefore, it is important to diagnose nasal osteoma when it is small in size, follow it up, and resect it when its size is appropriate for endoscopic surgery.
