肝脏原发性神经内分泌癌5例CT表现

CT features of primary hepatic neuroendocrine carcinoma in 5 cases

目的:总结肝脏原发性神经内分泌癌的CT表现,提高对该病的认识。方法:对手术或穿刺病理证实的5例肝脏原发性神经内分泌癌患者的CT资料,结合文献资料进行对比分析。结果:5例中肿瘤呈多发4例,表现为多发大小不等囊实性病变,1例为单发。CT平扫均表现为肝内低密度占位,病灶中央见较大范围的不规则更低密度区,边界清晰;1例单发者为囊性占位。增强扫描肿瘤实质部分表现为早期轻中度强化,门静脉期和延迟期呈轻度强化,中心更低密度区无明显强化。结论:CT在显示肝脏原发性神经内分泌癌上有一定的特征性,在该病的诊断和鉴别诊断中有一定价值。

Objective： To summarize the CT features of primary hepatic neuroendocrine carcinoma and improve its recognition. Methods： CT features of 5 cases with primary hepatic neuroendocrine carcinoma confirmed by pathology were retrospectively analyzed by combining with the literature data. Results： Multiple tumors in 4 cases, the features of which were cystic-solid lesions at different sizes and single tumor in 1 case were found. CT scanning showed low density placeholder with clear boundary in liver and more irregular low density area in the center of lesion. The single tumor was cystic lesion. Early mild-to-moderate strengthening in the solid part of tumor, mild strengthening during portal vein period and delay period and no obvious strengthening in more low density areas of center were found by CT enhancement scanning. Conclusions： The CT features of primary hepatic neuroendocrine carcinoma have certain characteristics, which has certain value on its diagnosis and differential diagnosis.
