School ager in motor vehicle accident with neck pain

CT of fracture of C2 vertebral body / Hangman fracture
Axial CT without contrast of the cervical spine (upper left) shows lucencies through both pedicles of the C2 vertebral body. Midline sagittal 2D reconstruction (upper right) shows anterior dislocation of the C2 vertebral body on the C3 vertebral body. Left sagittal (lower left) and right sagittal 2D reconstructions (lower right) again show lucencies through the bilateral C2 pedicles and bilateral anterior perching of the C2 inferior facets on the C3 vertebral body.

The diagnosis was fracture / dislocation of the C2 vertebral body with bilateral perched facets (Hangman fracture).
