Curtain sign (vertebral body mass)
Updates to Article Attributes
Body
was changed:
The Curtain sign (or Draped curtain sign) in neuroimaging refers to the appearance of a vertebral body mass that extends to the anterior epidural space.
The posterior longitudinal ligament is strongly attached to the vertebral body wall in its medial portion but it has a looser attachment laterally.
If a vertebral body lesion (e.g. a vertebral metastasis, vertebral hemangioma) extends posteriorly to the anterior epidural space, it displaces the posterior longitudinal ligament. However this is limited by that strong medial fixation, giving a bilobular intracanalar aspect in the axial images, which is commonly called Curtain sign (or Draped curtain sign).
