title: Radiographic features of osseous metastases of soft-tissue sarcomas.
abstract: In contrast to most other neoplastic processes of bone, in our study osseous metastases from soft-tissue sarcomas (STS) were more reliably detected by radiography than by scintigraphy. The radiographic manifestations of 65 skeletal metastases in 23 patients with STS were reviewed. Although most metastases (88%) were osteolytic, eight (12%) lesions were osteoblastic. The destructive patterns were geographic in 29%, moth-eaten in 55%, and permeative in 12% of the lesions. The axial skeleton was most commonly involved. In the long bones the diaphyses were the predominant sites of involvement. The bony cortex was frequently breached, with resultant soft-tissue swelling and pathologic fractures. Noteworthy features included subarticular location, involvement of the sacroiliac joint, and an expansile appearance.
