Infant who fell 3 feet out of bed onto a wooden floor

CT of an (not) accessory skull suture
3D reconstruction from CT without contrast of the brain (left) shows a linear straight lucency that connects to the left lambdoid suture. Coronal CT (right) shows the same linear lucency lying under a large subgaleal hematoma.

The diagnosis was a linear skull fracture and not an accessory suture of the skull based on the soft tissue swelling associated with the linear lucency.
