Pancreatic tumors are rare in children, resulting in limited information regarding their frequency and imaging appearances.
To review all pancreatic tumors seen in children over a decade at a large tertiary pediatric institution and to describe multimodality imaging findings.
We conducted a retrospective review of imaging studies performed in children with pancreatic tumors between January 2000 and December 2012, analyzing imaging features on available US, CT and MR examinations. We reviewed patient charts for clinical features, management and final diagnosis.
We included 23 children in this study. Of these, 12 had solid and papillary epithelial neoplasms (SPEN), 3 had neuroendocrine tumors, 3 had lymphoma, and 1 each had hemangioendothelioma, benign congenital cysts with adipose tissue, dendritic cell sarcoma, metastatic rhabdomyosarcoma, and lipoma. All children with SPEN were teenage girls. SPEN showed characteristic imaging features including well-defined margins with surrounding capsule, solid-cystic components and hemorrhage.
Pancreatic tumors are uncommon in children. SPEN is the most common tumor and is seen predominantly in teenage girls and shows characteristic imaging features.
胰腺肿瘤在儿童中较为罕见，因此有关其发病率和影像学表现的信息有限。
回顾在一家大型儿科三级医疗机构中 10 多年来所有儿童胰腺肿瘤，并描述其多种成像方式的影像学表现。
我们对 2000 年 1 月至 2012 年 12 月间在我院进行影像学检查的胰腺肿瘤患儿的影像资料进行了回顾性分析，分析了 US、CT 和 MR 检查的影像学特征。我们对患者的病历进行了复习，以了解其临床特征、治疗方法和最终诊断。
本研究共纳入 23 例患儿。其中，12 例为实性和乳头状上皮性肿瘤（SPEN），3 例为神经内分泌肿瘤，3 例为淋巴瘤，1 例分别为血管内皮细胞瘤、含脂肪组织的先天性良性囊肿、树突状细胞肉瘤、横纹肌肉瘤和脂肪瘤。所有 SPEN 患儿均为少女。SPEN 的影像学表现具有特征性，包括边界清楚伴包膜、实性-囊性成分和出血。
胰腺肿瘤在儿童中较为罕见。SPEN 是最常见的肿瘤，主要发生于少女，具有特征性影像学表现。
