A 65-year-old man has pointed out a hepatic tumor when he was rushed to the hospital because of disturbance of consciousness associated with hypoglycemia. Abdominal dynamic CT images showed a tumor, 2.5 cm in diameter, in S2/3 close to the umbilical portion of the portal vein, and it had enhancement in the arterial phase and became washout in the portal phase. We performed left lateral segmentectomy with a diagnosis of hepatocellular carcinoma. The tumor was histopathologically diagnosed as a Grade 1 neuroendocrine tumor(NET). As additional examinations could not detect a primary lesion in any other site, the tumor was considered as a primary hepatic NET(PHNET). PHNETs are rare and because of the possibility that an unknown primary lesion exists, we have to observe for years carefully.
一名65岁男性因低血糖伴意识障碍紧急送往医院时，发现肝脏有肿瘤。腹部动态CT图像显示，在靠近门静脉脐部的S2/3区域有一个直径2.5厘米的肿瘤，动脉期有强化，门静脉期呈廓清。我们诊断为肝细胞癌并进行了左外叶切除术。肿瘤经组织病理学诊断为1级神经内分泌肿瘤（NET）。由于其他检查未在任何其他部位发现原发灶，该肿瘤被认为是原发性肝脏NET（PHNET）。PHNETs很罕见，且由于可能存在未知的原发灶，我们必须多年仔细观察。
