3) In the cranium, widening of the diploic
space is demonstrated with a heterogeneous appearance.
3 cases had sclerotic mastoid while 1 case had diploic
10,11) It is postulated that this is owing to a peak in the vascularity of the diploic
system and the development of the frontal sinus between ages of 7 and 20 years.

Space of an Adult: Case Report.
6) This dynamic remodeling enlarges the diploic
4,5) Thrombophlebitis may take place in any of the diploic
veins in and around the temporal bone.
Also, the diploic
Breschet's veins are valveless, which allows blood and infected emboli to flow easily from the extracranial orbital and sinus area to the intracranial cavity.
There was involvement of skull with erosion of outer cortex and diploic
9] However, this method can increase the risk of dural tear, especially when drilling holes in the surrounding diploic
bone to allow for the passing of the securing sutures.
MRI of the head and spine revealed thickened diploic
space of the calvarial bones (Fig 4).
However, failure of the brain to grow causes other structures in the calvaria to grow inwards, accounting for hyper pneumatization of ipsilateral sinuses, increased width of the diploic
space, elevations of the greater wing of the sphenoid as well as the petrous ridge, shift of midline structures towards ipsilateral side and the sulcal prominence is absent.
Dural tears or skull fractures may allow the clot to be pushed into the diploic
bone of the skull or soft tissue where it may be more rapidly absorbed (1).
