A 49-year-old woman presented with a long history of moderate, dull pain in the right temporal region. The onset of symptoms was gradual, and her neurologist treated her for migraine, without success. After an episode of vertigo, she presented to her otorhinolaryngologist. A canal paresis of the right side was found on caloric testing. The results of pure-tone audiometry and auditory brainstem-evoked responses were normal. Computed tomography (Figure 1) and T2-weighted magnetic resonance imaging (Figure 2) showed a tumor adjacent to the petrous apex in the ventral part of the right middle cranial fossa, with smooth margins between the lesion and the temporal lobe of the brain.
