Quick Summary

Myelitis is the inflammation of the spinal cord. This condition can be caused by viral or bacterial infections, including mononucleosis, mumps, measles, chickenpox, tuberculosis, and herpes zoster.1

Symptoms of myelitis can include a painful girdle-like sensation around the trunk, loss of motor and sensory functions below the inflamed area, and impaired bladder control. Fever and meningism (stiff neck and headache) may also occur. The term "myelitis" itself comes from Greek roots meaning "bone marrow" and "-itis" for inflammation. An adjective form, "myelitic," describes something related to or causing myelitis.123
