Myelitis is a disease involving inflammation of the spinal cord, which disrupts central nervous system functions linking the brain and limbs. The name is derived from Greek myels referring to the 'marrow', and the suffix -itis, which denotes inflammation. Symptoms vary by region of the CNS affected, and include fever, headaches, tingling, pain or loss of feeling, and may extend to central or peripheral paresis and loss of bladder control. Meningeal signs may develop. Untreated myelitis may rapidly lead to a permanently damaged spinal cord.
