Causes of Vertebral scalloping






What is Vertebral scalloping ?
It 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:
1- achondroplasia
2- an intraspinal masses, such as:
                                                           -spinal astrocytoma
                                                           -ependymoma
                                                           -spinal schwannoma
                                                           -neurofibroma as seen in neurofibromatosis type 1
3- dural ectasia as seen in:
                                               -neurofibromatosis type 1
                                               -a hereditary connective tissue disorder such as
  •  Marfan disease
  •  Ehlers-Danlos disease
  •  osteogenesis imperfecta tarda
