Glial cell activation in the nerve roots of the spinal cord produces neuroinflammation, adhesions, and scarring. Treating patients within 48 hours after the onset of the syndrome provides a significant advantage in improving sensory and motor deficits as well as urinary and rectal function. Recent studies show that the frequency of lumbar arachnoiditis appears to be increasing due to an increasing amount of lumbar spine surgeries. 2. Space-occupying lesions, including disc herniation, trauma and tumor, within the spinal canal may compromise the nerve roots, causing severe clinical syndromes. Three resultant morphological patterns have been described on the basis of imaging 5: Rarely ossification/dystrophic calcification occurs and this is known as arachnoiditis ossificans. Efficacy of propentofylline, a glial modulating agent, on existing mechanical allodynia following peripheral nerve injury. Degenerated arthritic joints, trauma, or scoliosis that cause friction or compression between some of the nerve roots also may cause AA.

Nerve root or cauda equina inflammation can often be, however, observed on an MRI since inflammation causes edema (swelling), displacement, and the adherence or clumping of nerve roots to each other. The rationale and use of topiramate for treating neuropathic pain. To illustrate how neuroinflammation affects the spinal cord, we turn to a rare, but devastating example. We teach patients to stretch both upper and lower extremities several times a day. The arachnoid can become inflamed because of irritation from one of the following sources: Less commonly reported causes of arachnoiditis include: Arachnoiditis can be difficult to diagnose since its rare and not all healthcare providers are familiar with it.

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.. Common pathologic conditions of the spine, including herniated discs, spinal stenosis, and degenerative arthritis, may cause enough irritation to produce neuroinflammation in cauda equina nerve roots in the lumbar region.
