title: Primary osteosarcoma of the ribs: CT findings.
abstract: We report the CT appearance of primary osteosarcoma of the ribs in three patients. CT evaluation is important because this lesion may present a diagnostic dilemma on chest radiographs. The tumor should be suspected if CT demonstrates dense calcification within a mass that is centered in a rib.
