Duct penetrating sign

The duct-penetrating sign is a radiographic sign which can be useful in differentiating between focal pancreatitis (inflammatory pancreatic mass ) from pancreatic carcinoma.

Best description of positive sign is visualisation of a mass penetrated by an unobstructed pancreatic duct makes focal pancreatitis the most likely cause rather than pancreatic carcinoma. This sign is best appreciated by MRCP or more invasive modalities such a ERCP.

The duct-penetrating sign on MRCP is more helpful in differentiation between these entities than delayed  enhancement pattern on CT or MRI.
