How does cauda equina start?
Cauda equina syndrome can present in 2 ways: acute onset, where the symptoms and signs occur rapidly, and insidious onset, where the condition begins as lower back pain and slowly progresses to bowel and urinary incontinence. Cauda equina syndrome is most commonly caused by compression from a lumbar herniated disc.
What causes the compression of the thecal sac?
Spinal Canal Stenosis is another reason for the compression of the Thecal Sac. Injury or fracture of the Spinal Cord may also result in the compression of the Thecal Sac. Cysts can force the situation to be like this.
Why do I have pain in my thecal sac?
Thecal Sac Information. Sac compression or impingement diagnoses mean virtually nothing and are not usually the source of pain.

What is impingement upon the thecal sac?

What is narrowing of the thecal sac?
Narrowing of the central canal (called central stenosis) in the lumbar (low back) area can compress the thecal sac. This narrowing can cause pressure on the nerve bundle at the end of the spinal cord (cauda equina), or the individual nerves within the thecal sac.
What is compression of the dural sac?
Compression of the dural SAC. If we consider the picture of the spine and the dural SAC, it is evident that any deformation of the first can affect the second state . In other words, such pathologies of the spine, such as low back pain and herniated disc may be triggered by compression of the dural SAC.
What does effacement of the thecal sac mean?
Thecal refers to the covering of the spinal cord. Ventral refers. to the front. Sac is an enclosure, puch or cavity. Effacement means thinning. Ventral thecal sac effacement then is thinning at the front of the. covering that houses the spinal cord.
