Anteroposterior radiography revealed a plastic frontal sinus, Wormian bone
, and dysplastic zygomatic bone [Figure 1]e.
AIM: To find the incidence of wormian bone
. and compare the results with other study in India and abroad.
In addition, bones are classified into different types based on their shape, including long, short, flat, irregular, sesamoid, pneumatized, and sutural or wormian bones
. Long bones are tubular bones of the body, for example, humerus and femur and are relatively long and slender (1).
HCS is a multisystem disorder characterized by acro-osteolysis of distal phalanges, wormian bones
, severe osteoporosis with fractures, short stature, cardiac malformations, central nervous system involvement, dental anomalies, cystic renal disease, and craniofacial dysmorphism [4, 5].
Multiple Wormian bones
and poor mineralization of the cranium are noticeable on cranial radiographs.
Hajdu-Cheney syndrome (HCS) is a rare disorder which is characterized by developmental delay, craniofacial anomalies, congenital heart defects, hearing deficit, polycystic kidneys, and bone abnormalities, including progressive osteoporosis, acroosteolysis, wormian bones
, and abnormal bone fractures. Truncating mutations in Notch homolog protein 2 gene ( NOTCH2 ) are the principal cause of HCS.
The clavarium, base of skull and orbital rims were dense, widened sutures with intra sutural wormian bones
, small facial bones with hypoplastic maxillae and obtuse angle of mandible (Fig.
These include blue sclera, dentinogenesis imperfecta, hyperlaxity of ligaments and skin, hearing impairment, and presence of wormian bones
on skull radiographs.
X-ray skull showed multiple wormian bones
, widened sutures and patent anterior fontanel and occipitalization of C1 vertebrae [Figure 3].
