Bilateral idiopathic temporal bone meningoencephaloceles - An unusual presentation

Abstract: 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 magne… Show more

“…This part gets fractured in trauma with the resultant CSF leak and herniation of meninges and brain tissue into the sinuses. 5 Following a trauma, CSF leak may develop anytime within first few hours to months. In our case, CSF leak developed a couple of years later along with nasal obstruction.…”
