Urinoma masquerading as pancreatic pseudocyst.

In this article, we report on a patient with recurrent pancreatitis who had received multiple celiac plexus injections for control of pain, and then developed a cystic mass adjacent to the body and tail of the pancreas suggestive of a pancreatic pseudocyst. The cystic mass proved to be a urinoma. The distinction between pancreatic pseudocyst and urinoma was made by CT scan with intravenous contrast utilizing delayed films, which demonstrated leakage of contrast into the cystic structure.
