This study aims to investigate the manifestation of CT, MRI and dynamic enhanced scans for primary hepatic neuroendocrine cell carcinoma.
CT or MRI arterial and venous phase scan images of 19 cases of pathologically confirmed PHNEC were retrospectively analyzed.
14 cases (73.68%) with single lesion, 5 cases (26.3%) with multiple lesions, with an average diameter of 13.2 cm. Some 12 cases (63.16%) showed inhomogeneous enhancement, seven cases (36.8%) showed homogeneous enhancement, 13 cases (68.4%) demonstrated significant enhancement in the arterial phase, 13 cases (68.4%) had significantly enhanced portal venous phase including 7 cases (36.8 %) with portal venous phase density or signal above the arterial phase and 5 cases (26.3%) with the portal vein density or signal below the arterial phase. Seven cases (36.8%) had continued strengthened separate shadows in the center of the lesion. Thrombosis were not seen in portal veins.
CT and MRI images of liver cell neuroendocrine carcinoma have certain characteristics that can provide valuable information for diagnosis and differential diagnosis.
本研究旨在探讨原发性肝神经内分泌细胞癌的CT、MRI及动态增强扫描表现。
回顾性分析19例经病理证实的原发性肝神经内分泌细胞癌患者的CT或MRI动脉期及静脉期扫描图像。
单发病灶14例（73.68%），多发病灶5例（26.3%），平均直径13.2cm。12例（63.16%）表现为不均匀强化，7例（36.8%）表现为均匀强化，13例（68.4%）动脉期呈明显强化，13例（68.4%）门静脉期明显强化，其中7例（36.8%）门静脉期密度或信号高于动脉期，5例（26.3%）门静脉期密度或信号低于动脉期。7例（36.8%）病灶中心有持续强化的分隔影。门静脉未见血栓形成。
肝细胞神经内分泌癌的CT及MRI图像具有一定特征，可为诊断及鉴别诊断提供有价值的信息。
