| 摘 要： | 目的分析少见部位的原发性神经内分泌肿瘤(neuroendocrine tumor,NET)的影像学表现,以提高对该肿瘤的认识。资料与方法回顾性分析经病理证实的6例原发性NET的影像学资料,男5例,女1例,年龄51～71岁,平均58岁。肝脏、肾脏、膀胱、肠系膜各1例,胆囊2例。术前4例仅行CT检查,2例行CT和MRI检查。结果 6例中5例属于低分化神经内分泌癌(neuroendocrine carcinoma,NEC),分别位于肝、胆囊、肾及肠系膜,1例膀胱高分化NEC。肝脏原发性NET表现为大肿块伴周边多子灶,肺及腹膜后淋巴结转移,增强后呈不明显环形、分隔状强化。2例胆囊原发性NET分别为肿块型和厚壁型,肿块型1例巨大,随访晚期可见坏死,厚壁型1例黏膜中断,囊壁局限性增厚并肝脏浸润,2例强化均不明显,无腹腔内淋巴结转移。肾脏原发性NET表现为边界清楚的小结节,合并肝多发转移,增强后原发灶及转移灶均轻度强化。肠系膜NET中央坏死,增强后肿块呈轻度环形强化,灶周见肿大淋巴结,邻近肠系膜受牵拉呈辐射状。膀胱原发性NET表现为黏膜下密度不均匀结节影,MRI显示中央囊性部分呈长T1、长T2信号;病灶周壁及中间分隔呈短T...

| Abstract: | Objective To discuss the imaging features of primary neuroendocrine tumor(NET) in the rare site,and to improve its diagnostic accuracy.Materials and Methods Imaging data of 6 cases with primary NET proven by pathology were retrospectively analyzed.5 males and 1 female,aged 51 to 71,with an average age of 58.There were 1 case in Liver,kidney,bladder and mesenteric respectively,2 cases in gallbladder.Results 5 cases were poorly differentiated neuroendocrine carcinoma(NEC),which separately located in the liver... |
