Pancreatic carcinosarcoma: First literature report on computed tomography imaging

Figure 1 Computed tomography imaging of the abdomen the first time. The arterial phase (A) and portal venous phase (B) revealed a 2.2 cm × 2.0 cm well-circumscribed cystic lesion that was located at the pancreatic tail with a peripheral enhancing thick cystic wall that surrounded a non-enhancing low-attenuation area consistent with cystic fluid. We diagnosed it as mucinous cystadenoma.
