Solid pseudopapillary neoplasm of the pancreas in an adolescent: A case report and review of the literature

Figure 1 Sonographic images. A: Transverse sonographic view of the abdomen reveals a heterogeneous mass located in the epigastric region; B: Additional sonographic images depicting a portion of the mass (white arrow) adjacent to a normal-appearing pancreatic body and neck.

Figure 2 Computed tomography findings. A: Non-contrast axial computed tomography image demonstrating an encapsulated, solid-cystic mass (white arrow) in the pancreatic tail; B-D: Post-contrast axial (B) with sagittal (C) view showing enhancing solid (asterisk) and non-enhancing cystic component (triangle) of the mass and coronal (D) reconstructed image showing the ‘claw sign’ formed by the mass with the pancreatic parenchyma (black arrow).

Figure 3 Images of resected specimen following en-bloc surgical resection of the mass by distal pancreatectomy and splenectomy.

Figure 4 Histopathological examination of the surgical specimen. Hematoxylin and eosin staining demonstrating proliferation of monomorphic tumor cells with a pseudopapillary pattern.
