=====Other Spine Diseases=====

====More Than IVDD====

There is more to spine pathology than just IVDD! On this page, there will be case examples of non-IVDD pathology in the spine, and a list of any useful sequences.

====Discospondylitis====

Discospondylitis is an infection of the vertebral endplates and intervertebral disc, most commonly of bacterial origin. Some notable features are:

  * Collapse of the IVD
  * STIR/T2 hyperintensity
  * Contrast enhancement
  * Paravertebral inflammation or fluid like collections
  * sclerotic changes to vertebrae

Useful sequences:

  * STIR
  * T1 with and without fat saturation
  * T1 post contrast with fat saturation

====Arachnoid Diverticulum====

Some notable features of arachnoid diverticulum:

  * Scalpel sign
  * Gliosis
  * Lesion demonstrates CSF signal characteristics

Useful Sequences:

  * 3D Myelogram
  * 3D FIESTA-C / CISS
  * Sag T2 FSE

====Fibrocartilaginous Embolism (FCE)====

FCE is like a 'stroke' in the spinal cord; a small piece of IVD embolizes into a small spinal artery and occludes blood flow leading to ischemia or infarction in the spinal cord.

Notable Features:

  * Sharply Demarcated
  * Grey matter affected
  * Can be linear
  * Possible hemorrhage
  * Swelling of the spinal cord
  * Possible gad enhancement
  * T2/STIR hyperintensity

Useful Sequences:

  * T2 or STIR
  * T1 Post Gad
  * T2* if hemorrhage
  * DWI if specialized sequences are available
