Uncommon case of tibial bone infarction associated  with juvenile idiopathic arthritis.
Bone infarction refers to aseptic osteonecrosis occurring in the metaphysis and diaphysis of long bones. Hemoglobinopathies, sickle cell disease, and Gaucher's disease are usually found. Bone infarction is rarely idiopathic. Magnetic resonance imaging has proved to be more specific to identify bone infarction.We report an exceptional case of a unique idiopathic bone infarction of distal tibia, occurring unusually in a patient with juvenile idiopathic arthritis, without major risk factors of osseous infarct, and with atypical clinical and biological abnormalities.
