title: [Osteosarcoma and chondrosarcoma--radiographic differentiation with computerized tomography].
abstract: The purpose of this paper was to associate and compare the radiographic patterns of osteosarcoma and those of chondrosarcoma by means of computed tomography (CT). Computed tomographs of five cases of osteosarcoma and five cases of chondrosarcoma of the head and neck region were analyzed. The sensitivity of CT was calculated based on the results of histopathological examinations. We concluded that CT can facilitate the establishment of the final diagnosis since it is possible to distinguish the individual characteristics of osteosarcomas and chondrosarcomas in that exam.
