[摘 要] 目的：探讨胸壁原发恶性肿瘤的影像学特点对其定性的价值。方法：结合经手术、病理证实的6例胸壁原发恶性肿瘤，回顾性分析其X线和CT的影像学表现，再结合文献，提出对胸壁原发恶性肿瘤定性诊断有价值的影像学特点。结果：6例胸壁恶性肿瘤中，4例发生于胸壁软组织(脂肪肉瘤2例，纤维肉瘤1例，Askin瘤1例)，2例发生于胸壁骨组织(肋软骨肉瘤、肋尤文氏肉瘤各1例)。影像学表现：肿瘤向胸壁外生长3例，向胸壁内生长1例，同时向胸壁内外生长2例，其中5例有明显的胸壁骨质破坏，3例伴有肺转移。结论：X线及CT对胸壁原发恶性肿瘤的部位、范围以及肺是否受侵等有较大的诊断价值。[关键词] 恶性肿瘤；胸壁；X线摄影；体层摄影；X线计算机

Abstract：Objective To study the value of imaging characters in diagnosing primary malignant tumors of chest wall.Mothods Xray and CT findings of pathologically proved primary malignant tumor of chest wall in 6 cases were analysed,the findings enabling qualitative diagnosis were recommened.Results Of 6 patients,4 cases were originated from soft tissue of the chest wall(2 liposarcoma,1 fibrosarcom,1Askin tumor).And one case was Ewing's sarcoma and one case was costal chond rosarcoma.Imaging:the tumor invaded extratissue of chest wall in 3 patients and intra tassue of chest wall in 1 patient,both intra and extra tissue of chest wall in 2 patients.Chest bone hed destruction in 5 patients there were metastases of lung in 3 patients.Conclusion Radiography and CT are of some value in evaluating the location,extent and lung invasion of malignant tumor of chest wall. ......
