Sutural Hyperostosis

Sutural hyperostosis, also known as sutural sclerosis, is a normal variant in adults. It most commonly affects the coronal and lambdoid sutures as seen here.

In children, the most common cause of increased sclerosis of the sutures is craniosynostosis. Sutural sclerosis has also been reported in Torg-Winchester syndrome and NAO (nodules, arthropathy and osteolysis) syndrome.
