胸壁原发恶性肿瘤的影像学诊断

Imaging Diagnosis of Primary Malignant Tumor of Chest Wall

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。

Objective To study the value of imaging characters in diagnosing primary malignant tumors of chest wall. Mothods X-ray and CT findings of pathologically proved primary malignant tumor of chest wall in 6 cases were ana- lysed, 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 extra tissue 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. Oonclusion Radiography and CT are of some value in evaluating the location, extent and lung invasion of malignant tumor of chest wall.
