Spinal cord compression

3 things to know first

1. The spinal cord, not just a nerve root, is affected. This distinction matters.
2. The cause varies. Disc disease, bone changes, injury, infection, or a mass may create pressure.
3. Symptoms can be urgent. New walking difficulty, weakness, or bladder changes need prompt care.

What it is

The spinal cord carries signals between the brain and much of the body. Compression means tissue in the spinal canal presses on it. A report may describe flattening, displacement, or associated abnormal cord signal.

Why it appears on your report

MRI best shows the cord and surrounding soft tissue. CT may help show bone or acute injury. The report describes the level, degree of compression, possible cause, and whether the cord itself shows a signal change.

How serious is it

Mild image contact and clinically significant compression are different. Neurological symptoms and examination are essential. Delayed evaluation of progressive symptoms can risk lasting impairment.

When to seek care urgently

Seek emergency assessment for new or worsening limb weakness, trouble walking, loss of hand coordination, or bladder or bowel changes, especially if symptoms progress.

What usually happens next

1. A clinician reviews symptoms and neurological examination promptly.
2. The imaging level and cause are assessed.
3. Treatment may range from monitoring to urgent specialist care, depending on findings.
