Patient Data

Age: 12 months

Asymmetry of the skull.


Craniosynostosis involves the right side of the synchondrosis between the exoccipital and supraoccipital components of the occipital bone, reaching to the right posterolateral margin of the foramen magnum. No other sutural fusion is identified.

There is resultant flattening of the right occiput and narrowing of the transverse diameter of the occipital bone at the level of the foramen magnum so that the right mastoid is medially displaced and more prominent in its craniocaudal dimension. Compared with the facial bones, the foramen magnum, petrous bones and occiput are rotated towards the left. The occipitomastoid and squamous temporal sutures appear normal. There is no material asymmetry of the middle cranial fossae.
