This is the typical appearance of a Schmorl Node. Frequently they may have a sclerotic border. A Schmorl node is an intravertebral disc herniation due to vertical disc extension through a weakened vertebral body endplate. The differential includes acute compression fracture, degenerative endplate change, discitis, and limbus vertebrae (which is seen at the vertebral body corners).
