| 目的 探讨肝脏原发神经内分泌癌的影像表现特点。方法 回顾性分析经手术病理证实的3例肝脏神经内分泌癌的CT、MR资料,并与病理和组织学表现对照分析。结果 3例患者均为单发,其中2例位于肝右叶,1例位于肝左叶。肿瘤最大径分别为4.8 cm、6.7 cm、10.0 cm,均为实性肿物,其内伴不同程度低密度区,实性成分明显强化,囊性成分无强化,其内可见分隔;2例病变较大者,推压周围肝内血管使之移位;1例病变内可见多发强化和纡曲血管。MRI平扫T1WI呈略低信号,T2WI呈高信号,DWI呈高信号。结论 肝脏神经内分泌癌的影像表现有一定特征,多为单发实性肿物、其内伴不同程度低密度区域,实性部分明显强化。 |

| Objective To observe the imaging features of primary hepatic endocrine carcinoma. Methods Three patients with primary hepatic endocrine carcinoma proven pathologically were retrospectively analyzed. Results Single liver lesion was detected in all 3 patients, 2 in right and 1 in left lobe of liver. The maximum diameter of the masses was 4.8 cm, 6.7 cm and 10.0 cm, respectively. The masses were all solid with different extent of low density. The solid part enhanced greatly in contrast enhanced CT scanning, while the non-solid part did not. The bigger lesions pushed the vascular to move aside in 2 patients. Enhanced and circuitous vascular was observed in 1 lesion. Slightly low signal was noticed on MR T1WI , while high signal was found on T2WI and DWI. Conclusion CT and MR can show specific features of primary hepatic endocrine carcinoma, i.e. usually single solid mass with various low densities inside and the solid part enhancing dramatically. |
