Disc Herniation

A disc herniation means disc material extends beyond the normal disc margin. Depending on location and size, it may press on nearby nerves or the spinal canal, but many disc herniations are also found in people without severe symptoms.

Also seen as: herniated disc, disc extrusion.

If you are trying to place this wording inside the bigger picture of your report, start with the radiology findings hub and then compare it with the related symptom and report phrase pages below.

This term becomes more or less important depending on its size, location, severity, associated symptoms, and whether it is new compared with earlier imaging. Radiologists usually expect the finding to be read alongside the rest of the report instead of in isolation.

Disc bulges and herniations are common on spine imaging, especially with age and degenerative change.

• Age-related disc degeneration
• Mechanical strain or lifting injury
• Acute worsening of chronic disc disease
• Associated spinal stenosis or nerve compression

• The report mentions severe canal narrowing or nerve root compression
• Symptoms include weakness, numbness, or bowel or bladder changes
• There is progressive neurologic deficit

• Correlate imaging with symptoms and exam
• Manage some cases conservatively
• Consider specialist referral if nerve compression is significant

A radiology finding name can sound more definite than it really is. Many findings describe an imaging pattern, not a final diagnosis, and many turn out to be less urgent once doctors match the wording with your symptoms, exam, and any earlier studies.

• Left paracentral disc herniation at L5-S1.

• Disc extrusion causing mass effect on the traversing nerve root.
