[Osteoid osteoma of the foot. Apropos of 4 personal cases].

On the basis of four personal cases of osteoid osteomas of the foot, the authors study their frequency, their localization, and their clinical and radiological manifestations. They insist on the special difficulties of diagnosing this condition due to its atypical and uncertain radiological outline, and also on methods of further investigation : arteriography and especially isotopic scintigraphy.
