Jugular fossa meningocele

The jugular foramen is situated between the petrous portion of temporal and occipital bones and originates from persistence of the embryologic foramen lacerumposticus, the space between the basi-occiput and auditory canal.2 The cephaloceles are known to occur through the suture lines or junction of several bones.3 The skull base cephaloceles are classified into fronto-ethmoidal, spheno-orbital, sphenomaxillary, temporal, and nasopharyngeal types.3,4 Rare case reports of cephaloceles through the tegmen of petrous temporal bone, the greater wing of the sphenoid and the centre of the basilar occipital bones have been described.3,5,6 Our case, with its involvement of the jugular fossa, does not fit precisely within this classification. [...]another case of large skull-base meningo-encephalocele in a newborn has been described with a neck mass passing through the jugular foramen.7 Basal cephaloceles are rare, with an incidence of about 1 in 35,000 births.7 Basal cephaloceles are commonly occult and without any symptoms. [...]they may not be identified until adulthood, especially if there is no herniation of brain contents, as in our case.
