Findings:
- Large macrolobular multiloculated predominantly cystic lesion with a claw of pancreatic parenchyma around it, measuring 11 x 8cm on axial sequences.
- Heterogeneous T1 intrinsic signal with areas of proteinaceous material and peripheral/septal enhancement without a solid enhancing nodular component.
- No convincing main pancreatic duct connection.
- There is mass effect on adjacent structures, particularly the stomach.
- The splenic vein is not visualised with multiple perigastric collateral vessels.
Conclusion:
- Large macrolobular multiloculated 11 x 8cm cystic neoplasm arising from the pancreatic body/tail.
- Findings are favoured to represent a large mucinous neoplasm.
