The low rate of infection was due to repeated irrigation with sterilized saline and betadine before the operation and good reconstruction of the skull base, which protected the
calvarium from retrograde infection.
A heterogeneous lytic and sclerotic appearance to the
calvarium and cervical spine was noted.
Bone graft material is most commonly obtained from the mandible, iliac crest, tibia and
calvarium (Vermeeren et al.
with the
calvarium [the skull], in general, some people will actually try to change the presentation so that it's not vertex [head first], because when it's vertex presentation you never have enough dilation at the beginning of the case, unless you have real, huge amounts of dilation to deliver an intact
calvarium.
After removal of the
calvarium, cerebral edema was observed.
Skull fractures result from direct impact to
calvarium and are important because of their association with intracranial injury, which is the leading cause of traumatic death in childhood.
Pathophsiologically epidural hematoma occurs when there is separation of dura from the inner table of the
calvarium with the disruption and arterial and venous structures leading to the collection of blood in the available space but limited by the tight adhesion of dura to the suture lines 5.

Till date 12 such cases are reported and none had thoracic, vertebral or
calvarium involvement.
A confirmatory MRI performed at our fetal care institute at 29 weeks of EGA demonstrated the absence of the fetal
calvarium, missing the frontal, parietal, occipital, and temporal bones as well as the scalp.
The anteroposterior [Figure 2] and lateral skull radiographs [Figure 3] showed marked sclerosis with thickening of the orbital rims, skull base, and
calvarium with a loss of distinction between the cortex and medulla.
