Schmorl’s nodes or Schmorl’s nodules are protrusions of the cartilage of the intervertebral disc through the vertebral body endplate and into the adjacent vertebra.
Schmorl’s nodes can be detected radiographically, although they can be imaged better by CT or MRI.
Magnetic resonance imaging scans of a 50-year old storeman with right-sided sciatica for 1.5 months. He is homozygous for the Trp3 allele. Left, T1-weighted sagittal scan, right, T2-weighted sagittal scan. Schmorl’s nodes at the L1-2, L2-3, L3-4 and L4-5 levels. Grade 3 disc degeneration at the L1-2, L2-3 and L4-5 levels. Contained herniation at the L4-5 level. He has thoracolumbar Scheuermann’s disease with multiple Schmorl’s nodes and disc degeneration in the thoracolumbar region.Number of View: 4587
