Cleidocranial Dysostosis

  • Etiology: congenital
  • Imaging: hypoplasia / abscence of clavicles (lateral segment), delayed ossification of midline structures: cranium (Wormian bones, persistent sutures + fontanelles), pubic symphysis

Radiology Cases of Cleidocranial Dysostosis

Radiograph of cleidocranial dysostosis
AP and lateral radiographs of the skull (above) show multiple wormian bones in the lambdoid sutures. CXR AP (middle) shows complete absence of the clavicles bilaterally. AP radiograph of the pelvis (below) shows delayed ossification of the pubic bones giving the appearance of pseudo-diastasis of the symphysis pubis.
