Due to the sonographic features of the mass, neuroblastoma was initially diagnosed (Fig. 1).
6-month-old child with pancreatoblastoma. Contrast-enhanced CT demonstrates a well defined retroperitoneal heterogeneous mass, unevenly enhancing, with cystic areas consistent with hemorrhage or tumor necrosis, displacing the right kidney, bowel loops and the liver posterior, anterior and laterally respectively in A. Figures B and C show the superior mesenteric vessels and the remnant pancreatic parenchyma (arrows).

CT was performed to identify the origin and involvement of other abdominal structures (Figure 2, Figure 3, Figure 4).
6-month-old child with pancreatoblastoma. A, Coronal and B, sagittal (b) T2-weighted MR demonstrates a large heterogeneous mass with high signal intensity areas consistent with cystic necrosis and isointense areas compared to the spleen that represents the solid component of the tumor. Cephalad and lateral displacement of the liver and spleen respectively is shown.

Afterwards, the patient was taken to the operating room where a partial surgical resection of the mass was performed and histopathology confirmed the lesion to be a pancreatoblastoma (Figs. 5-6).
