+====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.

+====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
