Evidence of the subperiosteal origin of osteoid osteomas in tubular bones: analysis by CT and MR imaging.

摘要: A large series of patients with pathologically proven osteoid osteoma tubular bones was reviewed to determine the frequency a subperiosteal site origin.Thirty-eight cases that were included met two criteria: tumor located in bone, and lesion had been evaluated by CT scanning or MR imaging, both. The location categorized as intracortical, sub-periosteal, endosteal, medullary.Among 38 cases, 19 imaged scanning, 14 five both techniques. most common affected sites femur (n = 13), tibia 15), humerus 4). Among these 18 intramedullary, subperiosteal.Osteoid osteomas occurring surface are not rare. Indeed, many arising bone possibly originate later appear an intracortical lesion. This origin appears relate principally continual...
