2023 Friday Quiz 26 Answer

3D reformat CT (image 1), and coronal maximum intensity projection (image 2) of the cervical spine highlight the findings of atlantooccipital dissociation with posterior displacement of the C1 vertebral body (arrow) and increased space between the odontoid process and the occiput. In a neonate, nonaccidental trauma should be considered. A skeletal survey should be performed. In this patient, multiple posterior rib fractures (arrowheads image 3) and a classic metaphyseal lesion (dashed arrow) of the distal humerus (image 4) were also present.
