Transverse Myelitis
What is Transverse Myelitis?
Overview
Transverse myelitis (TM) is an acute inflammation of the spinal cord. Depending upon the level in the spinal cord at which it occurs, it can produce weakness and/or sensory changes in the arms and/or legs, muscle spasticity and blader& bowel dysfunction. Transverse myelitis is not a single disease entity; it may be produced by many underlying conditions, and is commonly seen in person with MS, NMO, or MOGAD, and may be the first presenting symptom of these conditions. Sometimes no underlying disease or cause for the TM is found; this is called idiopathic TM.
Who is Affected?
Transverse myelitis can occur at any age but is most commonly seen in children, adolescents, and adults between ages 20 and 50. Both males and females can be affected.
Certain forms of TM are associated with specific risk groups:
- Individuals with autoimmune disorders
- People with a history of viral or bacterial infections
- Patients with known demyelinating diseases such as MS, NMOSD, or MOGAD
- Children (who may develop post-infectious or MOG antibody–associated TM)
While TM is considered rare, prompt recognition is essential because early treatment can significantly affect outcomes.
Transverse Myelitis Symptoms & Causes
Symptoms
Symptoms of TM generally come on fairly acutely, i.e. over a matter of hours to a few days, and may involve the following:
- Back pain or neck pain
- Weakness and numbness or abnormal sensations in the arms or legs
- A “band-like” tightness around the torso
- Muscle spasms or stiffness
- Difficulty walking
- Changes in bladder and bowel control
- There may also be muscle spasms
Symptoms typically occur at and/or below the level of inflammation in the spinal cord. Severity can range from mild weakness to complete paralysis.
Causes
Transverse myelitis is caused by inflammation within the spinal cord. This inflammation may result from:
- Multiple Sclerosis
- Neuromyelitis Optica Spectrum Disorder
- MOG Antibody Disease
- Systemic autoimmune diseases such as lupus or sarcoidosis
TM can occur after viral or bacterial infections when the immune system mistakenly attacks the spinal cord. Sometimes transverse myelitis may occur after a vaccination.
In rare cases, infections can directly involve the spinal cord.
Occasionally, TM may be associated with an immune response triggered by an underlying cancer.
In some individuals, no cause is identified despite thorough evaluation.
Determining the underlying cause is critical because it influences long-term treatment decisions.
When to See a Doctor
You should seek medical evaluation immediately if you experience:
- Sudden weakness in the arms or legs
- Rapidly worsening numbness or tingling
- Difficulty walking
- Loss of bladder or bowel control
- Severe back pain with neurological symptoms
Call 911 or seek emergency care immediately if you experience:
- Rapid progression to paralysis
- Difficulty breathing
- Sudden inability to move your limbs
- Loss of sensation in the groin or genital area
- Severe confusion
Transverse myelitis is a neurological emergency. Early treatment improves the likelihood of recovery and reduces permanent damage.
Transverse Myelitis Diagnosis
Diagnosis begins with a detailed neurological examination and urgent imaging.
Evaluation typically includes:
- MRI of the spinal cord to identify inflammation
- MRI of the brain to evaluate for MS or related conditions
- Blood testing for autoimmune and infectious causes
- Antibody testing for AQP4 (NMO) and MOG antibodies
- Lumbar puncture (spinal tap) to analyze cerebrospinal fluid
MRI findings help determine the pattern and extent of inflammation. For example, long spinal cord lesions extending over three or more vertebral segments may suggest NMO rather than MS.
Because TM can be the first sign of a chronic autoimmune disorder, careful evaluation and follow-up are essential.
Transverse Myelitis Treatment & Outcomes
Treatment Options
Treatment for an acute attack of TM usually starts with high-dose intravenous corticosteroids to reduce inflammation.
Other modalities may be used if steroids are not effective. Additional therapies may include:
- Plasma exchange (PLEX)
- Intravenous immunoglobulin (IVIG)
After the acute attack, any residual symptoms or deficits are addressed with a combination of medications and rehabilitation strategies, including:
- Physical therapy
- Occupational therapy
- Medications for spasticity
- Pain management
- Bladder and bowel management
If an underlying cause is found as a cause for the TM, e.g. MS, then further treatment is directed at the underlying disease.
Patient Outcomes
Outcomes vary depending on:
- Severity of the initial attack
- Speed of treatment
- Underlying cause
Some individuals recover fully or nearly fully within months. Others may have persistent symptoms such as weakness, stiffness, neuropathic pain, or bladder dysfunction.
In idiopathic TM, many patients experience partial to substantial recovery. When TM is associated with an underlying autoimmune disease, long-term management focuses on preventing relapses.
Early treatment is strongly associated with better recovery.
Managing Transverse Myelitis
Recovery from transverse myelitis may take weeks to months. Active participation in rehabilitation plays a major role in maximizing recovery.
Daily management strategies include:
- Consistent participation in physical and occupational therapy
- Stretching exercises to reduce stiffness
- Strength training as recommended by your care team
- Bladder management plans
- Skin care to prevent pressure injuries if mobility is limited
- Medication adherence
- Reporting new neurological symptoms promptly
- Emotional support and counseling if needed
Maintaining a healthy lifestyle — including adequate sleep, balanced nutrition, and stress management — supports neurological recovery.

Learn More About Transverse Myelitis
No. TM is a clinical syndrome (spinal cord inflammation). It can occur as part of MS, but it may also occur independently or with other autoimmune conditions.
No. TM itself is not contagious.
It can recur if associated with conditions like MS, NMOSD, or MOGAD. Idiopathic TM is often monophasic (one-time event), but careful follow-up is important.
Recovery may begin within weeks but can continue for months or even years. Most improvement occurs within the first 3–6 months.
Prognosis varies. Some individuals recover fully, while others may have lasting weakness, stiffness, or bladder dysfunction. Outcomes depend on the severity of inflammation, how quickly treatment is started, and whether an underlying autoimmune disease is present. Early treatment and rehabilitation significantly improve the likelihood of recovery.
