Imaging pitfalls of pancreatic serous cystic neoplasm and its potential mimickers

Figure 7 A 45-year-old female with branch duct type intraductal papillary mucinous neoplasm mimicking oligocystic serous cystic neoplasm (also see Figure 6). A: Magnetic resonance cholangiopancreatography shows a cystic mass (arrow) in the body of the pancreas. The communication with the main pancreatic duct (MPD) is not apparent even with the source images (not shown). There is no downstream MPD dilatation; B: Axial T2-weighted single-shot fast spin-echo magnetic resonance image with fat saturation demonstrates a mass showing a cyst-by-cyst pattern (arrow); C: Endoscopic retrograde pancreatography shows the cystic lesion to be opacified (arrow), representing communication with the pancreatic duct.
