Wormian bones
Discussion
-
The term wormian bone is technically reserved for intrasutural bones in the area of the lambda
-
Mention them only to point out to referring doctors that these are NOT fractures, for which they are often mistaken
-
Although wormian bones can have an association with a number of different disorders (predominantly skeletal dysplasias), consider them a normal variant unless you see more than 10-20
