Clinical Image

This is a 52 years-old male patient that presented at the clinic complaining of a hearing loss at his left side since the past 2 years. He denied tinnitus, dizziness, earache, otorrhea or trauma. He used to work in agricultural production and had controlled hypertension. He denied any family history of hearing loss. Physical examination did not present any changes. An audiometry was requested and a sensorineural hearing loss in the left ear was observed (Figure 1), and a MRI was performed. A contrast enhanced (T1 weighted (A)) and heterogeneously hyperintense (T2 weighted (B)) lesion was observed within the internal auditory canal on the left side (Figure 2 - arrow), characteristically compatible with acoustic neuroma. After discussion, the patient decided for observation instead surgery.
