[Roentgen morphology of secondary, metastatic bone tumors (author's transl)].

General and specific roentgen morphologic criteria of secondary metastases are described and characteristic appearances of metastatic disease demonstrated by examples. Early detection of tumor metastases and limitations of different radiologic methods are discussed. Various dynamic ways of development in bone metastasis during the course of malignant disease are described and different biologic growth properties of various tumors documented by different reaction of bone tissue. The high diagnostic value of radiologic follow up examinations for control of therapeutic results is emphasized. This applies for judgement of secondary metastatic as well as for the underlying malignant disease. Analysis of the bone structure of the Tela ossea of macro- and microradiologic films is presented for illustration.
