title: Pitfalls in the ultrasonographic diagnosis of the pancreatic pseudocyst.
abstract: A pseudocyst of the pancreas typically presents ultrasonographically as a cystic structure in the upper abdomen. We have seen numerous cases which presented similar sonographic features suggestive of a pancreatic pseudocyst in which this diagnosis proved false. A knowledge of the ultrasonographic differential diagnosis of the pancreatic pseudocyst therefore becomes important.
