目的：探讨原发性肝脏神经内分泌癌（PHNEC）的CT特征。方法回顾性分析7例经手术病理证实的PHNEC的CT检查资料，均行平扫及增强检查。结果7例患者均无肝硬化，单发3例，2例位于肝右叶，1例位于肝左叶；4例多发，表现为单个较大肿块伴多发子灶。CT平扫均为实性低密度肿块或结节，边界清晰。动态增强扫描5例动脉期不均匀明显强化，其中3例门脉期持续强化呈不均匀稍高密度，2例门脉期开始廓清呈低密度。2例单发病灶动脉期轻度强化，门静脉期持续强化，延迟期呈相对低密度。结论 PHNEC的CT表现具有一定的特征性，CT检查有助于术前诊断。

Objective To investigate the CT features of primary hepatic neuroendocrine carcinoma (PHNEC). Methods Unenhanced and dynamic contrast-enhanced CT of 7 patients with pathologically confirmed PHNEC was analyzed retrospectively.Results Of 7 patients without liver cirrhosis, the tumors were solitary (3) in the right lobe (2) and left lobe (1), or single largelesion with multiple satellite nodules (4). On CT, 5 lesions were low-density masses or nodules with well-defined boundary andheterogeneous marked contrast enhancement in the arterial phase progressively enhancing (3) or washing out in the portal venous phase(2). The remaining 2 solitary lesions enhanced slightly in the arterial phase continuing into the portal venous phase and washing outin the parenchymal phase. Conclusion CT features can aid pre-operative diagnosis of PHNEC.
