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.
与大多数其他骨肿瘤形成过程不同，在我们的研究中，软组织肉瘤（STS）的骨转移通过放射照相术比闪烁扫描术能更可靠地检测到。回顾了23例STS患者中65处骨骼转移灶的放射学表现。虽然大多数转移灶（88%）为溶骨性，但有8处（12%）病灶为成骨性。29%的病灶破坏模式为地图状，55%为虫蚀状，12%为浸润性。轴骨最常受累。在长骨中，骨干是主要受累部位。骨皮质常被破坏，导致软组织肿胀和病理性骨折。值得注意的特征包括关节下位置、骶髂关节受累和膨胀外观。
