Figure 11(A, B).

Minor suture synostoses. Endocranial 3DCT volume rendered images show symmetric (A) and asymmetric (B) minor sutural synostoses. There is symmetric fusion of the anterior and posterior intra-occipital synchondroses (arrowheads in A), associated with a small foramen magnum. Note also asymmetric fusion of the right posterior intra-occipital synchondroses (arrow in B) resulting in rotation of the posterior skull base axis towards the side of the abnormally fused suture
