title: [Computed tomographic differential diagnosis of primary pelvic osteo-, chondro- and Ewing's sarcomas].
abstract: The value of CT for the differential diagnosis of primary malignant tumours in the pelvis was investigated in the case of three types of tumour: osteosarcomas, chondrosarcomas and Ewing's sarcomas. A total of 78 CT examinations in 29 patients was used. The results show that CT, using suitable techniques (high resolution etc.) constitutes a valuable diagnostic method for differentiating these bone tumours. This applies not only for the localisation of the tumour and for defining its extent, but also for showing the morphology of intra- and extra-osseous soft tissue components and their patterns of calcification. It is possible to recognise patterns of growth and of tissue destruction that are typical of individual tumours.
