Imaging pitfalls of pancreatic serous cystic neoplasm and its potential mimickers

Figure 12 A 65-year-old female with solid serous adenoma. A: Unenhanced axial computed tomography shows a large mass with central calcification (arrow) in the tail and body of the pancreas. The lesion is isodense to the normal pancreatic parenchyma; B: The pancreatic parenchymal phase shows avid tumor enhancement (arrow); C: The equilibrium phase shows the mass to be high density (arrow) relative to the normal pancreatic parenchyma, representing persistent enhancement (no wash-out); D: Magnetic resonance cholangiopancreatography does not show the mass or cystic spaces; E: Microscopic view of the resected specimen shows a solid nest of tumor cells with abundant fibrous stroma.
