Preschooler
with short stature. AP radiograph of the lumbar spine (left) shows progressive narrowing of the distance between the pedicles descending through the lumbar spine (interpedicular narrowing). The lateral radiograph of the lumbar spine (right) shows shortened pedicles leading to narrowing of the anterior-posterior diameter of the spinal canal (spinal stenosis) and that the vertebral bodies have some anterior wedging and posterior scalloping.The diagnosis was achondroplasia.

Preschooler
with short stature. Lateral radiograph of the spine shows kyphosis of the thoracolumbar spine and shortened pedicles, posterior scalloping of vertebral bodies and anterior beaking of vertebral bodies.The diagnosis was achondroplasia.
Vertebral scalloping is a concavity to the posterior (or less commonly anterior) aspect of the vertebral body when viewed in a lateral projection. A small amount of concavity is normal, as is concavity of the anterior vertebral body (see vertebral body squaring).
Posterior scalloping
Causes of posterior scalloping include the following, organized by mechanism :
- localized increased intraspinal pressure due to
- intradural spinal mass
- ependymoma, most commonly myxopapillary ependymoma
- astrocytoma
- paraganglioma
- neurofibroma as seen in neurofibromatosis type 1
- schwannoma
- lipoma
- intraspinal cysts
- intradural spinal mass
- dural ectasia
- neurofibromatosis type 1, especially with lateral thoracic meningocele
- hereditary connective tissue disorders
- congenital skeletal disorders
- achondroplasia due to small spinal canal
- mucopolysaccharidoses
- acromegaly
A useful mnemonic can be found here.
Anterior scalloping
Causes of increased anterior scalloping include:
- retroperitoneal lymphadenopathy, including (but not limited to):
- chronic leukemia
- lymphoma
- tuberculosis
- abdominal aortic aneurysm
- Down syndrome
