Radiology Cases of Wormian Bones

Radiology Cases of Wormian Bones in 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.

Radiology Cases of Wormian Bones in Congenital Hypothyroidism

Radiograph of Wormian bones
Lateral radiograph of the skull shows a relatively enlarged sella and multiple Wormian bones.

Radiology Cases of Wormian Bones in Osteogenesis Imperfecta Type III

Radiographs of osteogenesis imperfecta Type III
AP and lateral radiographs of the skull (above) show multiple wormian bones in the coronal and lambdoid sutures. CXR AP (lower left) shows multiple bilateral acute rib fractures. AP radiograph of the lower extremities (lower right) shows multiple bilateral acute and chronic fractures of the bilateral femora and tibiae and fibulae causing bowing deformities of the lower extremities.
Radiographs of osteogenesis imperfecta Type III
Lateral radiograph of the skull (upper left) shows multiple wormian bones in the coronal and lambdoid sutures. CXR AP (upper right) shows multiple bilateral healing rib fractures. AP radiographs of the upper (lower left) and lower (lower right) extremities show multiple bilateral healing fractures of the extremities causing bowing deformities of all of the extremities.
