目的 探讨胸壁转移瘤的CT诊断和鉴别诊断价值。方法 回顾分析 114例胸壁转移瘤的CT表现 ,同时与 12例胸壁良性肿瘤和瘤样病变、9例胸壁结核和 3例胸壁原发性肿瘤作一对比。结果 胸壁转移瘤的CT表现 :胸壁肿块呈分叶状 6 6例 ,平扫时肿块为软组织密度或略低于软组织密度各 78和 36例 ;16例增强扫描肿块均呈不均匀强化 ;肋骨呈鼠咬状和截断状 5 2例 ,肋床侵蚀 17例 ,肋骨膨胀 4例 ;肿块撑开相邻肋骨 49例 ,肿块边缘(有短条状、针絮状和网格状影 )模糊的 6 9例。结论 CT对胸壁转移瘤具有重要诊断和鉴别诊断价值 ,但是也有一定局限性
Objective To investigate the value of CT diagnosis and differential diagnosis of chest wall metastases. Methods The CT findings of 114 cases of chest wall metastases were retrospectively analyzed. At the same time, they were compared with 12 cases of benign and malignant chest wall tumors, 9 cases of chest wall tuberculosis and 3 cases of primary chest wall tumors. Results The CT findings of chest wall metastases showed that the chest wall lobes were lobulated in 66 cases, the mass at soft tissue scan was slightly lower than the soft tissue density at 78 and 36 cases respectively, and all the 16 cases showed uneven enhancement. 5 cases of rat bite and truncation, 17 cases of rib bed erosion and 4 cases of rib expansion. The masses of the adjacent ribs were expanded in 49 cases. The margin of the tumor (short strip, needle-like and grid-like shadow) 9 cases. Conclusion CT has important diagnostic and differential diagnostic value in the metastasis of the chest wall, but it also has some limitations
