We present a patient with pancreatoblastoma along with a discussion of various cross-sectional imaging features. The tumor was a large multilocular cystic mass with solid components in the left retroperitoneal space. There were fine internal echoes on ultrasonography, and the signal intensity was high on both T1- and T2-weighted MR images in most of the locules, suggesting the presence of hemorrhagic debris. Among the various retroperitoneal organs displaced by the tumor, only the pancreatic tail was inseparable from the mass, suggesting that the pancreatic tail was the origin of the tumor. Pancreatoblastoma should be included in the differential diagnosis when a large left upper quadrant mass with these imaging features is seen in infants and young children.
我们报告一例胰腺母细胞瘤患者，并讨论其各种横断面成像特征。肿瘤为左腹膜后间隙的一个巨大多房囊性肿块，伴有实性成分。超声检查显示内部有细小回声，在大多数房腔内，T1加权和T2加权磁共振图像上信号强度均较高，提示存在出血性碎屑。在被肿瘤推移的各种腹膜后器官中，只有胰尾与肿块无法分离，提示肿瘤起源于胰尾。当婴幼儿出现具有这些成像特征的左上腹巨大肿块时，胰腺母细胞瘤应列入鉴别诊断。
