What does it mean when MRI says sequestered disc measuring 7mm by 15mm?

A sequestered disc is a type of herniated disc in which the inner gel-like material (nucleus pulposus) of the disc has completely ruptured through the outer layer of the disc (annulus fibrosus) and is now separate from the rest of the disc.

In your case, the MRI report indicates that you have a sequestered disc measuring 7mm by 15mm. This means that the herniated portion of the disc is 7mm in height and 15mm in length.

A sequestered disc can put pressure on the nerves near the spine, causing pain, numbness, and weakness in the arms or legs. The treatment for a sequestered disc will depend on the severity of your symptoms and may include conservative treatments such as physical therapy, medication, and injections, or surgical intervention.

It is important to discuss your MRI results with your doctor to determine the best course of treatment for you.
