Spinal cord compression as a result of Rosai–Dorfman disease of the upper cervical spine in a child

Background Rosai–Dorfman disease is characterized by massive painless cervical lymphadenopathy, but can also include nasal obstruction, tonsillar enlargement, or hearing abnormalities. The disease occurs most often in the third and fourth decades. Most authors have suggested that it represents either an autoimmune disease or a reaction to an infectious agent that has yet to be discovered. Less than 50 cases of central nervous system involvement have been reported.
