Can arachnoiditis be seen on MRI without contrast?

On repeat myelography or MRI, the nerve roots of the cauda equina appear thickened, clumped, and adherent to the periphery of the thecal sac. Enhancement of the roots may occur following intravenous contrast administration. Arachnoiditis is now rarely seen with the use of water-soluble, nonionic contrast agents.

Can MRI detect arachnoiditis?

Spinal arachnoiditis can be diagnosed by myelography, computed tomography, and by magnetic resonance imaging (MRI) in combination with clinical symptoms and history taking.

Can arachnoiditis be misdiagnosed?

They are often misdiagnosed with failed back surgery syndrome, complex regional pain syndrome (a chronic pain condition that usually affects the arms or legs), fibromyalgia, slipped discs, sciatica, and other back-related issues.

In some people. it may affect the bladder, bowel, and sexual function. Very severe arachnoiditis can result in paralysis of the legs.

How does arachnoiditis affect the brain?

Cerebral arachnoiditis: Cerebral arachnoiditis affects the membrane surrounding the brain, and often causes intense headaches. Hereditary arachnoiditis: A rare form of arachnoiditis, this is due to genetic defects in the meninges.

Is arachnoiditis an autoimmune disease?

The arachnoiditis seems likely to have been existing long before the history of boat trauma. The etiology for this spontaneous or primary arachnoiditis is unknown. This is possibly related to an autoimmune disorder that links it (via blood) with chronic arachnoiditis (i.e, systemic inoculation-toxin overload).
