Unfused anterior and posterior arches of C1

Discussion:

Incidental finding of unfused anterior and posterior arch of C1 in an elderly female who had CT to exclude fracture after fall. Congenital abnormalities can create confusion, especially among non-radiologists, when a patient is assessed in the setting of trauma. The presence of cortication along the non-fused bone margins as well as a typical appearance, permit categorical exclusion of an acute fracture.
