Inflammatory pseudotumor presenting as a cystic tumor of the pancreas.

Inflammatory pseudotumor (IPT) of the pancreas occurs rarely. Eighteen cases have been described in the English literature. In all previous patients IPT of the pancreas presented as solid pancreatic mass. We are reporting a case of IPT presenting as a cystic mass of the pancreas, which has not been described previously. A review of IPT of the pancreas and a discussion regarding the management of pancreatic cystic neoplasm is provided.
