[Osteoid osteoma. (Plain films, angiography and scintigraphy in fifty patients) (author's transl)]

The radiological diagnosis and differential diagnosis of osteoid osteomas was considered in relation to a series of 50 histologically verified cases. In twenty, angiography had been performed and scintigraphy was carried out seven times. Various problems in the diagnosis of osteoid osteomas in relation to their localisation within bone (cortical, medullary, sub-periosteal, subarticular) and within the skeleton (near the hip, in the hand or foot, in the spine and in flat bones) are discussed.
