Common Causes Of Syringomyelia

Hemorrhage

A hemorrhage of the spinal area can be caused by several different factors including a spinal cord tumor, continuous anticoagulant therapy, spinal trauma, vascular malformation, or idiopathic bleeding. It is also not uncommon to see a spinal bleed due to prior spinal surgery or procedures. When a spinal bleed occurs in the spinal cord, it causes instrasyringeal pressure inside of the spinal channel. Similar to other causes of fluid-filled cysts inside the spinal cord, the pressure causes disruptions in the fluid velocity and flow of the cerebrospinal fluid from the excess of blood present. Often hemorrhagic spinal cord cysts are not filled with a fluid similar to the cerebrospinal fluid, but are filled with bloody fluids due to the nature of the syrinx instead. A hemorrhagic-derived diagnosis of syringomyelia is one of the least commonly seen causes for the disorder, and hemorrhagic-induced syringomyelia can be rare in comparison to the number of cases derived from other causes.
