Intraosseous disc herniation -or Schmörl nodes (SN)- are a herniation or prolapse of the nucleus pulposus of the intervertebral disc through the vertebral plate and into the adjacent vertebral body. They are usually associated with vertebral deformities, such as Scheuermann’s disease, or rheumatic diseases, such as ankylopoietic spondylitis. In general, they are spontaneous and asymptomatic findings, and there are only a few reported cases of symptomatic nodes. The etiology is supposedly related to a weakened spinal plate due to trauma or repeated stress. When the node is acute or recent, it can be difficult to differentiate a benign degeneration from a malignant infiltration or infection. In this paper, we discuss the unusual case of a painful Schmörl node in a man with no relevant history and a masked metastatic lumbar spinal tumor originated from pancreatic cancer. We performed a literature review.
