摘要
目的:通过12例肺肉瘤样癌患者的临床表现,CT征象及手术后病理分型来评估CT对肺癌肉瘤的诊断价值。方法:将手术证实的12例肺癌肉瘤的临床表现、病理类型与CT特征对照分析。结果:肺肉瘤样癌的CT表现显示具有肺癌和肉瘤的双重特征。既具有癌块的边缘征象,如分叶、毛刺等周边浸润征象,增强扫描又具有肉瘤的强化表现,如较厚的环状强化、肿块中央常为不规则的密度减低区。结论:肺内圆形或椭圆形较大肿块,增强扫描肿块呈不规则环状强化,中央显示不规则密度减低区,酷似肉瘤的CT表现,而其边界不甚规则,边缘不光整,有分叶、毛刺等浸润表现时应考虑为肺肉瘤样癌之可能。胸部CT增强扫描对肺肉瘤样癌的初步诊断具有一定的临床价值。
Objective To investigate the diagnostic values of CT by studying the imaging and clincopathologic features of primary pulmonary sarcomatoid carcinoma(PSC).Methods The CT findings and clinicopathologic manifestations of PSC proved by operation and pathology in 12 cases were reviewed retrospectively.Results The CT findings of PSC had both lung cancer and sarcomatous features.The features including the marginal sign of cancer,such as lobular sign and spiculated sign,and the contrast-enhanced CT findings of sar...
