Abstract: 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.
