摘要 目的总结原发性肝脏神经内分泌肿瘤(PHNEN)的有效诊断方法。方法对1例PHNEN患者的临床资料,包括临床表现、实验室检测指标(如肝功能、甲胎球蛋白)、核磁共振检查结果及病理检查结果进行回顾性分析。结果该患者间断腹痛腹胀1年,加重半个月。肝功能:γ-谷氨酰基转移酶281 U/L,谷丙转氨酶383 U/L,谷草转氨酶216 U/L,总胆红素35.8μmol/L,直接胆红素21.6μmol/L;肿瘤标记物:甲胎蛋白20.68 ng/mL。上腹部核磁共振提示肝左右叶交界区可见团块混杂信号灶,大部分呈长T1长T2信号灶,内壁可见类圆形稍短T1混杂T2信号灶,动脉期可见不均匀明显强化,门静脉期呈明显强化,强化范围增大,内可见分隔影,延迟期略有降低,肝胆期仍呈稍高信号,界限欠清楚,约为6.8×5.6 cm,其内可见多发无强化的囊性灶。术中冰冻及术后石蜡切片均显示为PHNEN。结论病理学检查(SSTR-2、CD56、CgA、Syn、Ki-67等免疫组化指标阳性)加上影像学检查(胃肠镜、腹部CT及MRI、B超、PET/CT等均未发现肝外原发病灶)是确诊PHNEN的主要诊断方法。
