What does Paracentral disc protrusion mean?

What does Paracentral disc protrusion mean?

Subarticular (Lateral Recess or Paracentral): When the disc extrudes between the spinal cord and the foramen (the space through which the nerves exit the spinal canal).

What is a Paracentral disc herniation?

Paracentral disc herniation is the most common (90-95%) type of herniation affecting the lower nerve root at L4-L5. When a large part of your disc displaces beyond its normal limit it is termed as bulging disc. But in disc herniation, less than 25% of disc dislodgment occurs.

What is the difference between a disc bulge and a disc protrusion?

The nucleus presses against the annulus, causing the disc to bulge or prolapse outward. The bulged disc material is still contained within the annulus. But in some cases, the nucleus pushes completely through the annulus and squeezes out of the disc. This is called a disc herniation or protrusion.

What does it mean to have a paracentral disc protrusion?

This is called a bulging disc or herniated disc, depending on the severity of disc damage. However, when a paracentral disc protrusion occurs, the disc extends toward the center of the spine and protrudes into the space between the spine and the spinal cord. If the disc impacts a nerve root near the spinal cord, severe pain and symptoms can occur.

How is paracentral disc extrusion diagnosed by a CT scan?

How is Paracentral Disc Extrusion Diagnosed? The best way to diagnose Paracentral Disc Extrusion is by way of radiologic studies in the form of a CT scan or an MRI. This will give the accurate picture of the internal structures of the spine and will clearly show the disc herniation and the nucleus pulposus impinging the nerve root.

What are the symptoms of a paracentral disc herniation?

Reviewed By: Pramod Kerkar, MD, FFARCSI. Paracentral Disc Extrusion is a pathological condition in which there is seepage of the nucleus material of a herniated disc on right or left side of the middle portion of the disc. The disc herniation often protrudes into foramina and causes foraminal stenosis.

What are the symptoms of a disc protrusion in the neck?

Symptoms and Diagnosis. 1 Pain in the Cervical (Neck) Region. If a protruding disc irritates nerves in the neck region, pain may be felt in the neck itself, but it may also 2 Pain in the Thoracic (Mid Back) Region. 3 Pain in the Lumbar (Lower Back) Region.

This is called a bulging disc or herniated disc, depending on the severity of disc damage. However, when a paracentral disc protrusion occurs, the disc extends toward the center of the spine and protrudes into the space between the spine and the spinal cord. If the disc impacts a nerve root near the spinal cord, severe pain and symptoms can occur.

How does the protrusion of the disc affect the spinal cord?

The resulting protrusion of the disc protrudes into the canal of the spinal cord, squeezing, irritating and infringing the nerve fibers and vessels passing there. In addition, the function of the vertebra itself may be impaired.

How is Paracentral Disc Extrusion Diagnosed? The best way to diagnose Paracentral Disc Extrusion is by way of radiologic studies in the form of a CT scan or an MRI. This will give the accurate picture of the internal structures of the spine and will clearly show the disc herniation and the nucleus pulposus impinging the nerve root.
