[Medullary osteoid osteoma. A pathogenic discussion].
OBJECTIVE
Medullary osteoid osteoma is exceptional. We report one case.


METHODS
A 15-year-old patient presented osteoid osteoma localized in the medullary canal of the tibial shaft, associated with intense medullary and cortical hyperosteosis.


CONCLUSIONS
The origin of the osteogenesis in medullary osteoid osteoma could be a localized hemodynamic change involving venous congestion with stimulation of periosteal venous drainage.
