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 carcinoid sarcoma in the liver is extremely rare. We found a 56-year-old male patient diagnosed with primary liver carcinosarcoma by pathological immunohistochemistry. CT scan showed that the mass located in the right lobe of the gallbladder fossa, low density, spiral CT multi-phase enhanced scan showed a mixed mass density, uneven enhancement, solid lesions were significantly enhanced, the mass visible multiple low-density nodules, the edge of the mass A ring-shaped enhancement, mass violations of the gallbladder wall and transverse colon. Primary liver carcinosarcoma CT characteristics of the lack of performance, difficult to diagnose before surgery.
