a-b: Segmented hemivertebra in two patients: The 3D reconstruction from a non-contrast CT of the spine (a) and coronal T1-weighted MR image of different levels of the thoracic spine (b) demonstrate a laterally located wedge of bone composed of half a vertebral body (marked by asterisks). Note that there is associated scoliotic deformity, more pronounced on a. This variety of hemivertebra, being clearly separate from its neighbour above and below, has the most potential for impacting spinal curvature. c-e: Semisegmented hemivertebra in 16 year old: 3D reconstruction (c) and coronal and oblique sagittal reconstructions from a non-contrast CT of the spine (d and e) demonstrate a laterally located wedge of bone composed of half a vertebral body (marked by asterisks). Note that this variant is attached to its neighbouring inferior vertebra and has only the superior disc space adjacent to it
