Solid pseudopapillary neoplasm of the pancreas in a young male with main pancreatic duct dilatation: A case report

Figure 1 The plain phase, the arterial phase, the portal vein phase, and the delayed phase. A: Contrast-enhanced computed tomography shows a 40-mm-diameter, hypovascular mass in the head of the pancreas, the inside is uneven, and the boundaries are relatively clear (white arrows); B-D: The lesion heterogeneously and slightly enhances as the phase progresses. The main pancreatic duct upstream of the mass is severely dilated (yellow arrows).
