Gastric intramural pseudocyst with associated gastric outlet obstruction: recognition and management.

Pancreatic pseudocyst is a well-recognized complication of pancreatitis. Most pseudocysts either resolve spontaneously or are amenable to internal drainage. Occasionally, the pseudocyst extends to distant areas within the abdominal cavity or may invade a nearby anatomic structure. Direct extension into the stomach is infrequently noted both radiographically and clinically. Recognition and management of this entity are described.
