横纹肌肉瘤骨侵蚀较少见，本文报告４例并复习国内文献报告的８例，对其ｘ线表现进行了分析、总结。横纹肌肉瘤骨侵蚀的Ｘ线表现较为复杂，有骨质破坏，骨膜反应和软组织肿块。为便于认识，作者将骨质破坏分为广泛溶骨型、渗透状、虫蚀状和骨皮质外压吸收四型，这四型可混合存在。通过分析这１２例可见横纹肌肉瘤骨侵蚀多见于四肢骨和颅面骨，病理上以胚胎型、腺泡型为主者多见。 The bone erosion of rhabdomyosarcoma is less common. This article reports 4 cases and reviewed 8 cases of domestic literature reports. The x-ray findings were analyzed and summarized. The X-ray appearance of rhabdomyosarcoma bone erosion is more complex, with bone destruction, periosteal reaction and soft tissue mass. For ease of understanding, the authors divided bone destruction into extensive osteolytic, osmotic, worm-eaten, and cortical external pressure-absorbing type IV. These four types can be mixed. Analysis of these 12 cases of rhabdomyosarcoma can be seen in bone erosion in limbs and craniofacial bone, pathologically more common in embryonic, alveolar type.
