F1
There was a large round-shaped occipital defect at the vertex with dimensions of 4 x 3 cm and two lesser ones at the frontal vertex with dimensions of 1 x 2 and 1 x 1 cm [Figures 1 and 2].

F2
There was a large round-shaped occipital defect at the vertex with dimensions of 4 x 3 cm and two lesser ones at the frontal vertex with dimensions of 1 x 2 and 1 x 1 cm [Figures 1 and 2].
The CT scan, confirmed the defects which involved both bone and skin layers, and revealed suture diastasis with thinning and hypoplasia of fronto-parietal bones

ACC involving the patient's father and siblings. At birth, the patient had an extensive round-shaped hemorrhagic bullae with dimensions of 10 x 5 cm above the fronto-occipital regions of the scalp [Figures 4 and 5].
MRI confirmed that the defect included scalp and skin layers and revealed complete loss of continuity of the dermal and subcutaneous tissues
