[Computer-tomographic evaluation of tumors of the pelvis (author's transl)].

Some cases selected from a group of 35 patients with bone tumors of the pelvis (16 primary, 15 secondary malignant neoplasia, 3 semimalignant tumors, and 1 benign tumor) serve to demonstrate the significant information gained by computed tomography. In bone tumors of the pelvis neither conventional radiography nor angiography render reliable information about the extent of the tumor. Computed tomography is helpful in showing the intra- and extraosseous extent of the lesion, in demonstrating the relationship of the tumor to the organs in the neighbourhood, in measuring of volume and density and discovering the recurrence of tumor.
