Abstract

Meningoceles are a common radiological feature found in cases of idiopathic intracranial hypertension (IIH). Rarely, they can affect the facial canal within the petrous temporal bone, leading to symptoms such as facial nerve palsy, hearing loss or meningitis. This is the first case report that describes bilateral facial canal meningoceles involving the tympanic segment of the canal. Prominent Meckel's caves were also seen on MRI, a feature commonly associated with IIH.
