原发于肝脏的癌肉瘤极为罕见.我们发现一例56岁男性患者,经病理免疫组化确诊为原发性肝脏癌肉瘤.CT平扫检查发现肿块位于肝右叶胆囊窝旁,呈低密度,螺旋CT多期增强扫描显示肿块呈混合密度,强化不均匀,实性病灶明显强化,肿块内部可见多发低密度结节,边缘呈环形强化,肿块侵犯胆囊壁及横结肠.原发性肝脏癌肉瘤CT表现缺乏特征性,术前诊断困难.

Primary liver carcinosarcoma is extremely rare.We report a case of liver carcinosarcoma in a 58-year-old man,which was identified by pathologic and immunohistochemical(IHC)examinations.Plain CT scans showed a hypodense mass in the right liver lobe adjacent to the gallbladder fossa.The triple.phase contrast CT scans showed a mixed density mass with inhomogeneous enhancement.Multiple cystic nodules with irregular rim enhancement of the margin located in the tumor.The gallbladder wall and transverse colon were involved.CT presentations of Iiver carcinosarcoma were unspecific and the preoperative diagnosis is difficult.
