Purpose

Several types and subsets of spinal dysplasias have been documented and can have similar apperances. The purpose of this poster is to review a case and discuss the important details to narrow the differential.

Methods & Materials

Multiple contiguous axial images of the spine were obtained. 3-D reformatted images of the spine were made at a separate workstation. Multi-sequential multi-planar MRI images of the spine were obtained. A full skeletal survey was obtained.

Results

Abnormal vertebral bodies demonstrating platyspondyly throughout the cervical, thoracic, and lumbar spine with associated severe thoracolumbar scoliosis. Os odontoideum and spina bifida occulta at L5. Severe degree of bilateral coxa vara with marked deformity of the femoral necks and overriding of both greater trochanters. Marked dysplastic changes and irregularity are also noted at the acetabula which appear flat. Skeletal survey reveals several areas of metaphyseal irregularity and splaying.

Conclusion

Multiple etiologies present with platyspondyly. The vertebral body appearance can be seen with either spondyloepiphyseal dysplasia and spondylometaphyseal dysplasia. Further review of the skeleton is warranted to further narrow down the differential. Given the diffuse metaphyseal irregularity and splaying, relative sparing of the epiphysis, and severe bilateral coxa vara spondylometaphyseal dysplasia would be at the top of the differential.
