We report an unusual combination of features comprising delayed tooth eruption and closure of the anterior fontanel as the sole presenting features in a child with cleidocranial dysplasia (CCD). Radiological survey revealed the presence of wormian bones in the skull, pseudoepiphysis at the base of the bilateral second metacarpal, and midline ossification defects at pubic symphysis in the presen...

We had the opportunity to examine the cranium of a young woman found at the well-known Neolithic site of Ali Koshon the Deh Luran plain in southwestern Iran. It has previously been claimed that her head shows traces of modification,a practice which can be termed as either cultural or artificial cranial modification. Here, we describe several macroscopiccharacteristics of the modified crania and...

Foramina parietalia permagna or enlarged parietal foramina are a rare variant estimated to be less than 1 in 25,000 cases. Out of 150 dry macerated skulls studied one skull showed 2 large parietal foramina measuring 17.38 x 27.67 mm (right) and 15.31 x 25.46 mm (left) in size. Between them, across the sagittal suture, was a transverse communicating suture interrupted by 3 very small wormia...

A unique connective tissue disorder characterised by the triad of dentinogenesis imperfecta, blue sclerae, and multiple wormian bones has been identified in 20 members of three generations of a large kindred of mixed ancestry in South Africa. The skeletons of affected subjects were moderately osteoporotic but, apart from minimal bowing of the femora and some vertebral flattening in late adultho...
