Avidan A, Gomori M, Davidson E. Nerve root inflammation demonstrated by magnetic resonance imaging in a patient with transient neurologic symptoms after intrathecal injection of lidocaine. Although the term cauda equina syndrome has traditionally only referred to the acute compression of the nerve roots, some practitioners have used the term chronic cauda equina syndrome when bladder and bowel dysfunction, pain, and some paraparesis coexist. In addition, cauda equina syndrome is a rare but well-recognized complication of longstanding ankylosing spondylitis. In addition to adhesions and scarring, AA patients may develop some interference with spinal fluid flow. Whatever the mechanism, patients may develop periodic blurred vision and severe headaches due to increased fluid pressure.

Cleveland Clinic is a non-profit academic medical center. A number of measures are recommended to hopefully promote neuroprotection and neurogenesis (nerve growth) of damaged nerve roots: replacement of deficient hormones; use of the neurohormones, human chorionic gonadotropin and oxytocin; high-protein/anti-inflammatory diet; vitamin B; and pentoxifylline with tocopherol (vitamin E).

Cauda Equina Syndrome Symptoms, Treatment, Causes, Prognosis Although the mechanism is somewhat unclear, patients may apparently develop some interference with spinal fluid flow. The cause, in my opinion, is that nerve root clumping, scarring, and adhesions form a physical road block for fluid flow. Although early treatment is required to prevent permanent problems, cauda equina syndrome may be difficult to diagnose. It is my personal observation that stable pain relief is difficult to attain in AA patients until a potent and aggressive neuroinflammation regimen is in place. You'll find that both physical and emotional support is essential. Although the term arachnoiditis simply implies inflammation of the arachnoid lining of the meninges or thecal sac, the major pathologic abnormality in the majority of cases is neuroinflammation of the nerve roots in the cauda equina. Once glia cells in nerve roots produce neuroinflammation, they may form adhesions and scars that may cause nerve roots to stick together or clump and adhere to the arachnoid lining.. It most commonly affects the nerves of your lumbar (low back) and thoracic spine (middle back). Saddle anethesia sensory disturbance, which can involve the anus, genitals and buttock region.
