[Imaging aspects of sphenoid during development].
To show the different steps of ossification and pneumatization of the sphenoid bone in children in order to emphasize normal anatomic variations. CT scanners and MRI studies of children up to 15 year old performed for various craniofacial conditions, without suspected involvement on cranial growth, are presented. The normal process of the ossification, of the closure of the synchondroses and of the pneumatization is demonstrated. Some examples of congenital abnormalities are also shown. The knowledge of these normal steps and variations is essential, in order to properly evaluate traumatic or congenital situations, but is also helpful for the diagnosis of bone dysplasias and bone marrow diseases (tumor or hematologic disorders).
