Unusual cause of dizziness: Occult temporal lobe encephalocele into transverse sinus

摘要

Encephaloceles are rare manifestations, and occur most frequently in the occipital region. Temporal lobe encephaloceles are defined as pathological herniations of brain parenchyma through dura mater and bone, and they involve the middle cranial fossa or lateral temporal cranial vault. The majority of cases of temporal encephalocele reported in the literature to date have presented with complaints of epilepsy or ear disturbance (e.g., hearing loss, otorrhea, otitis media with or without rhinorrhea, and recurrent meningitis) [1].
