Imaging pitfalls of pancreatic serous cystic neoplasm and its potential mimickers

Figure 2 A 57-year-old female with mixed microcystic and macrocystic serous cystic neoplasm. A: Coronal T2-weighted single-shot fast spin-echo magnetic resonance (MR) image with fat saturation shows a cystic mass (large arrow) in the pancreatic head consisting of central microcysts and peripheral macrocysts. The small arrow indicates dilatation of the upstream main pancreatic duct. B: Axial T1-weighted gradient-echo MR image with fat saturation shows high intensity fluid in the macrocysts (arrows), representing hemorrhage. Hemorrhage may be seen in macrocysts, although it is uncommon.
