摘　　要：目的　分析胸壁原发恶性肿瘤的CT表现 ,探讨CT对其定位、定性及鉴别诊断的价值和限度。方法　对经手术、活检证实的 7例原发胸壁恶性肿瘤的CT表现 ,结合病理所见进行回顾性分析。结果　 7例胸壁恶性肿瘤中 ,5例发生于胸壁软组织 (脂肪肉瘤和纤维肉瘤各 2例 ,横纹肌肉瘤 1例 ) ,2例发生于胸壁骨组织 (胸骨骨肉瘤、肋软骨肉瘤各 1例 )。CT表现 :肿瘤向胸壁外生长 3例 ,向胸壁内生长 2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 ,4例伴有肺转移。结论　CT对胸壁原发恶性肿瘤的部位、范围以及肺脏是否受侵等有较大的诊断价值。Objective To study the value and limitation in localized,gualified and diffenential diagnosis of primary malignant tumor of chest wall by CT.Methods CT featares of primary malignant tumor in chest wall comfired by pathology in 7 cases were analysed combined with pataologic findings.Results Of 7 patients,5 cases were originated from soft tissue of the chest wall ( 2 liposarcoma,2 fibrosarcoma ,one rhadomyosarcoma).And 1 case was osteosarcoma of sternum and one case was costal chondrosarcoma.CT imaging:the tumor invaded extra-tissue of chest wall in 3 patients and intra tassue of chest wall in 2 patients,both intra and extra tissue of chest wall in 2 patients.Chest bone hed destruction in 5 patients there were metastases of lung in 4 patients.Conclusion CT scan is of some value in evaluating the location,extent and lung invasion of malignant tumor of chest wall.
