Synostic posterior plagiocephaly. This is caused by fusion of the bones on the side and the back of the head. It results in a flattened area on the side of the synostosis; the back of the head shifts to the unaffected side; and the area near the ear (mastoid process) may bulge. It is very rare and can be confused with deformational posterior plagiocephaly.
