How do I know if I have Lipomyelomeningocele?

Lipomyelomeningocele is a form of closed spinal dysraphism where a fatty mass extends through a defect in the spine, often causing tethering of the spinal cord. You can identify potential signs by watching for visible skin markers on the lower back, such as dimples or fatty lumps, alongside neurological changes like weakness, numbness, or bladder control issues.

What are the common signs of Lipomyelomeningocele?

Because Lipomyelomeningocele is a congenital condition, many cases are identified at birth due to visible skin abnormalities in the lumbosacral region. However, some individuals remain asymptomatic until adulthood. Common indicators include:

• Visible skin markers: A fatty mass, hairy patch, dimple, or skin tag on the lower back.


• Neurological changes: Progressive weakness in the legs or foot deformities.


• Sensory issues: Numbness or tingling in the lower extremities.


• Bladder and bowel dysfunction: Sudden changes in frequency, urgency, or control.

When should I suspect I have Lipomyelomeningocele?

If you notice a persistent lump or unusual skin markings on your lower back combined with unexplained neurological symptoms, you should seek a clinical evaluation. While normal variations like a simple skin dimple are common and often benign, a Lipomyelomeningocele requires professional imaging to rule out spinal cord tethering. It is important to distinguish between minor back pain and symptoms related to the spinal cord, such as progressive gait changes.

How is Lipomyelomeningocele diagnosed?

To investigate Lipomyelomeningocele, your physician should order an MRI of the entire spine. This is the gold-standard diagnostic tool. If you are struggling to get a referral, present your specific symptoms clearly: "I am concerned about potential tethered cord syndrome related to Lipomyelomeningocele due to [list symptoms] and would like an MRI to investigate."

What are the red flags for urgent care?

Seek immediate medical attention if you experience sudden, severe loss of bowel or bladder control, or rapid, significant weakness in your legs. These may indicate acute spinal cord compromise associated with Lipomyelomeningocele that requires urgent neurosurgical consultation.

Next steps

• Consult a neurologist or neurosurgeon specializing in spinal dysraphism.


• Request an MRI of the lumbosacral spine to visualize the spinal cord.


• Connect with the 40 members of the DiseaseMaps.org community living with Lipomyelomeningocele to share experiences.


• Keep a symptom log to document the progression of any neurological changes.
