摘要
目的:探讨肺肉瘤样癌的CT表现及病理特点。方法:回顾性分析19例(男16例,女3例,平均年龄63岁)经手术病理证实的肺肉瘤样癌患者的CT表现和病理资料。结果:19例中右肺12例,左肺6例,1例为两肺多发肿块。中央型3例,周围型16例。19例均为肺内实质肿块,肿块最大直径2.5～8.3cm,密度不均匀,增强后10例表现为边缘环形强化,内部强化不明显。14例周围型肿块位于胸膜下,其中11例侵犯胸膜。术后病理多形性癌14例、梭形细胞癌2例、巨细胞癌2例、肺母细胞瘤1例。免疫组化CK阳性18例,EMA阳性7例,Vimentin阳性19例。结论:肺肉瘤样癌CT表现具有一定特征,确诊仍需依靠病理学检查。
Purpose： To investigate CT findings and pathological features of pulmonary sarcomatoid carcinoma. Methods： CT images of 19 patients （16 males, 3 females, mean age 63） with pathologically proved pulmonary sarcomatoid carcinoma were analyzed retrospectively. Results： Of 19 patients, 12 located in the right lung, 6 located in the left lung and 1 located in both sides of the lung with multiple masses. There were 3 cases of central type and 16 cases of peripheral type, their diameters ranged from 2.5cm to 8.3cm. The density of the tumors were heterogeneous. Ten of them showed irregular peripheral contrast enhancement heterogeneously after administration of contrast medium with no enhancement in the center part of the tumor. Fourteen cases of peripheral type tumors were subpleural, 11 cases with pleural invasion. The histopathological result showed that, 14 were pleomorphic carcinoma, 2 were spindle cell carcinoma, 2 were giant cell carcinoma and 1 were pulmonary blastoma. The immunohistochemical result showed that, CK was positive in 18 cases, EMA was positive in 7 cases, and Vimentin was positive in 19 cases. Conclusion： Although PSC has some characteristic CT imaging findings, the final diagnosis requires pathological examination.
