Meningoencephaloceles (MECs) occur due to herniation of brain tissue through a bony defect in the skull base. They can be spontaneous or acquired. These are secondary to trauma, infection or neoplasia. Adult-onset spontaneous or idiopathic MECs are rare. Temporal bone MECs can present with watery discharge from the ear, conductive hearing loss or symptoms of meningitis like headache, fever, vomiting or seizures. These symptoms mimic chronic suppurative or serous otitis media. Computed tomography scan and magnetic resonance imaging differentiate between them. Awareness of this disease entity is necessary for early detection to avoid complications. We report a case of bilateral idiopathic temporal bone MECs with a rare presentation of autophony as the chief complaint. The differentiating features on computed tomography scan and magnetic resonance imaging and the surgical management are discussed.
