摘要：原发性肝脏神经内分泌肿瘤（primary hepatic neuroendocrine tumor，PHNET）是
一种罕见的肝脏恶性肿瘤，缺乏特征性表现，临床误诊及漏诊率高。本文回顾性分析
1例经病理证实的PHNET患者的影像及临床资料并复习相关文献，从正电子发射计算机
体层显像（positron emission tomography and computed tomography，PET/CT）、磁共振
成像（magnetic resonance imaging，MRI）、计算机体层成像（computed tomography，
CT）的影像特点以及病理学特征进行总结，以提高对该病的认识，诊断PHNET的重点
是通过多种检查排除肝外原发灶，最终结合病理进行综合判断。

Abstract: Primary hepatic neuroendocrine tumor (PHNET) is a rare malignant liver tumor that lacks
characteristic manifestations and has a high rate of clinical misdiagnosis and missed diagnosis. This
article retrospectively analyzed the imaging and clinical data of a patient with PHNET confirmed by
pathology, and reviewed relevant literature to summarize the imaging characteristics and pathological
features of positron emission tomography and computed tomography (PET/CT), magnetic resonance
imaging (MRI) and computed tomography (CT), in order to improve the understanding of the
disease. The key to diagnosing PHNET is to exclude primary lesions outside the liver through various
examinations, and finally diagnosed based on pathological features.
