摘要
目的：探讨螺旋CT和MRI对原发性肝脏神经内分泌癌（PHNEC）的诊断价值。方法：回顾性分析7例经手术病理证实的肝脏原发性神经内分泌癌患者的CT和MRI资料，比较分析其影像学特征。结果：7例PHNEC患者共发现10个病灶，5例为单发，2例多发。6个病灶位于肝右叶，2个病灶位于肝左叶，2个病灶较大于肝左右叶交界区，肿瘤直径1．0～13．0cm，8个病灶内部见液化坏死或囊变，动态增强后肿瘤实性部分动脉期强化明显，门脉期持续强化，囊性部分及液化坏死部分不强化；2个病灶较小，内未见囊变及坏死，动态增强后动脉期明显强化，门脉期为等信号。结论：PHNEC的cT和MRI表现具有一定特征性，CT和MRI有助于术前诊断。
Objective： To study the value of CT and MRI in the diagnosis of primary hepatic neuroendocrine carcinoma （PHNEC）. Methods：The CT and MRI materials of seven cases with pathology proved PHNEC were retrospectively ana lyzed. The imaging features were studied. Results：Of the seven cases,altogether ten lesions were revealed,single lesion was found in 5 cases, multiple lesions were found in 2 cases. The location was right hepatic lobe （6 lesions）, left lobe （2 lesions） and 2 large lesions seated across right and left lobe of liver. The diameter of the masses ranged from 1.0cm to 13.0cm,intratumoral liquefaction,necrosis or cystic change could be revealed in 8 lesions. Marked enhancement could be seen in the solid parts of tumors in arterial phase, kept consistent in portal venous phase, no enhancement was assessed in the necrosis and cystic components. Two lesions with small size didn＇t have necrosis or cystic component, showing marked enhancement in arterial phase and remained isointense in portal venous phase. Conclusion： Certain CT and MRI characteristics could be revealed in PHNEC,and is useful for the diagnosis before surgery.
