Schmorl's nodes occur when the cartilage of the
intervertebral disc protrude through the vertebral body
endplate into the adjacent vertebra. These protrusions may
contact the bone marrow of the
vertebra and lead to inflammation. These protrusions may also be responsible for necrosis ( condition of death) of the vertebral bone. They may or may not be symptomatic, and it is
questionable whether or not it will cause back pain.
The T-2
weighted image on the left shows a S
chmorl's node in the lumbar region and has protruded into the vertebral body of L-3. Although
Schmorl's node can be seen
radiographically, the
modality of choice would be
either MRI or a CT scan for a much better and more diagnostic image.
It is believed that
Schmorl's nodes develop after some type of back trauma, but the fact is that
Schmorl's nodes are not well understood.
