How is Tethered Spinal Cord Syndrome diagnosed?

Tethered Spinal Cord Syndrome is primarily diagnosed through clinical neurological examination followed by magnetic resonance imaging (MRI) of the spine to visualize the low-lying conus medullaris. Because symptoms can be subtle or mimic other conditions, diagnosis often requires a multidisciplinary approach led by neurosurgeons or pediatric neurologists.

How is Tethered Spinal Cord Syndrome diagnosed?

The diagnostic process for Tethered Spinal Cord Syndrome typically begins with an evaluation of clinical signs such as back pain, gait abnormalities, or bladder and bowel dysfunction. A specialist will perform a physical exam looking for cutaneous markers on the lower back, such as a dimple, hair tuft, or fatty lump, which are often associated with Tethered Spinal Cord Syndrome.

What imaging tests are required?

Imaging is the gold standard for confirming Tethered Spinal Cord Syndrome. The following tests are essential for an accurate evaluation:

• MRI of the Total Spine: The most critical tool, used to identify a low-lying conus medullaris (typically below the L2 level) and the presence of a thickened filum terminale or lipoma.


• Ultrasound: Often used in infants under six months old as a screening tool before the posterior vertebral arches have fully ossified.


• Urodynamic Studies: Frequently ordered to assess bladder function, as neurological changes in Tethered Spinal Cord Syndrome often manifest as urinary retention or incontinence.

Why is the "diagnostic odyssey" so difficult?

Many patients face a frustrating diagnostic odyssey because symptoms of Tethered Spinal Cord Syndrome are often non-specific and can be confused with scoliosis, tethered cord variants, or orthopedic issues. It is common for patients to see multiple specialists before an MRI confirms the diagnosis. If you feel your concerns are being dismissed, seek a second opinion from a neurosurgeon who specializes in congenital spinal anomalies.

Which specialists manage this condition?

Diagnosis and management are best handled by a team including a pediatric or adult neurosurgeon, a neurologist, and a urologist. At DiseaseMaps.org, 41 people with Tethered Spinal Cord Syndrome have shared their experiences, highlighting the importance of finding a care team that understands the progressive nature of the condition.

Next steps

• Consult a neurosurgeon with specific expertise in spinal dysraphism.


• Request a full-spine MRI if you have persistent neurological symptoms or lower back cutaneous markers.
