Schmorl's node may cause an increased FDG activity.

Schmorl's node is an intraspongious disc herniation, which is formed within the vertebral body through a cartilaginous endplate. Schmorl's nodes are commonly seen at radiographic examination or autopsy. Schmorl's nodes are generally considered to be asymptomatic. In this article, we demonstrate the incidental findings of moderate FDG uptake in the Schmorl's node.
