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.. Become a Gold Supporter and see no third-party ads. AA may originate with any irritant that may affect some of the 2 dozen nerve roots in the cauda equina. The irritant may be a toxin, trauma, infection, or friction between nerve roots. Once irritation occurs in the nerve roots, activated glial cells initiate a neuroinflammatory response. Like all inflammation, a modest amount is protective and curative, but too much causes tissue destruction with adhesive and scarring elements. Use a catheter to completely empty your bladder three or four times a day. Unfortunately, AA may develop, resolve, and become a progressive, debilitating disease.

Medical procedures required to treat spinal pathologic abnormalities may accelerate or possibly initiate a neuroinflammatory process in cauda equina nerve roots. Most surgeons recommend decompression as soon as possible, within about 8 hours of the onset of symptoms if symptoms develop suddenly. 4. Understanding AA requires some knowledge about the anatomy of the cauda equina, or horses tail. About two dozen nerve roots emanate and hang down from the end of the spinal cord known as the conus medullaris (Figure 1). The nerve roots within the thecal sac are quite organized.
