A 75-year-old woman presented with a 4-month history of constant dizziness and gait disturbance. Her medical history included type 2 diabetes mellitus, essential hypertension, stable ischemic heart disease, and Paget disease, which mainly affected the vertebra. She had no history of subjective hearing impairment or similar events.
Physical examination revealed normal otoscopic findings with no nystagmus, a left-sided sixth nerve palsy, and a mass in the right nasal cavity. Axial computed tomography of the brain and paranasal sinuses showed a calcified, nonhomogeneous, well-demarcated, space-occupying lesion in the sphenoidal and posterior ethmoidal air cells (Figure 1 and Figure 2).
