回顾性分析8例经病理证实的肺部原发肉瘤样癌的多层CT表现,并复习文献.右肺上叶5例、下叶2例,左肺上叶1例;1例因肿块巨大未分型,其余7例均为周围型;4例见假包膜,1例见粗大钙化,肺门、纵隔淋巴结转移2例,空洞1例,1例伴广泛小叶间隔增厚及磨玻璃密度影,2例肿块有深分叶及毛刺;1例仅行CT平扫,余7例行平扫及增强CT检查,其中6例呈进行性强化,5例强化不均,肿块呈厚薄不均的环形强化,4例可见“浮冰样”表现.肺部原发肉瘤样癌以上叶胸膜下区常见;“浮冰样”表现对肉瘤样癌有一定诊断价值.

Retrospective analysis of multi-slice computed tomography (MSCT) manifestations were conducted for 8 cases of pathologically confirmed primary pulmonary sarcomatoid carcinoma.And the relevant literature was also reviewed.The lesion sites were right upper lobe (n =5),lower lobe (n =2) and left upper lobe (n =1).One case was difficult to distinguish because of its huge mass and the remainder was all peripheral.With pseudocapsule (n =4),coarse calcification (n =1),hilar & mediastinal node metastasis (n =2) and cavity (n =1).The manifestations included extensive lung alveolar septal thickening & ground glass (n =1) and massive deep leaf & glitches (n =2).The scans were non-enhanced alone (n =1) and non-enhanced & enhanced (n =7).Six cases had shaped enhancement while another 5 uneven thickness of annular enhancement.And 4 cases had "floating-ice" change.Primary pulmonary sarcomatoid carcinoma is common in subpleural lung lobe.And the "floating-ice" sign is valuable in the diagnosis of sarcomatoid carcinoma.
