Imaging of Pelvic Bone Tumors

Pelvic tumors are rare entities. Metastases are the most common malignant tumors and can derive mainly from breast, lung, prostate, kidney, and thyroid cancers. Primary benign and malignant tumors may arise from bone or bone marrow in cases of hematological malignancies. There is a broad spectrum of pathology involving the pelvis and differential diagnosis could be a challenge. However, with the proper analysis of the imaging workup for a patient with a suspected tumor, the diagnosis can be narrowed. Evaluation should always begin with a conventional plain radiographs and cross-sectional imaging (CT and MRI), up to a biopsy as final step of the staging.
