[A neonate without claviculae].

A 1-week-old girl, term born after a non-complicated parturition, presented with abnormal clavicles. At physical examination small and short clavicles were seen, as well as a widened anterior and posterior fontanelle. An X-ray of the thorax showed hypoplastic clavicles and an X-ray of the skull showed delayed ossification of the bones, hypoplasia of the maxilla and extra teeth. This led to the diagnosis 'cleidocranial dysplasia'.
