title: Pancreatic pseudocyst associated with eating disorder.
abstract: We describe a patient with an eating disorder and hyperamylasemia originating from the salivary glands, who developed pancreatitis with a huge pancreatic pseudocyst. A 40-year-old woman was referred for the treatment of an eating disorder that had persisted for 9 years. She was admitted with abdominal pain, diarrhea, and nausea. She had bilateral parotid enlargement with marked elevation of total serum amylase level (3288 IU/l; normal range, 60-220) and an isolated increase of salivary isoamylase activity. After her symptoms resolved, oral intake of food was commenced. She subsequently complained of abdominal pain; this was associated with a slight elevation of serum pancreatic isoamylase and lipase levels, and a huge pancreatic pseudocyst was detected. Percutaneous drainage of the pseudocyst was successful. Endoscopic retrograde cholangiopancreatography demonstrated irregularity of the pancreatic duct. Based on these findings, the final diagnosis was parotid enlargement and acute exacerbation of chronic pancreatitis associated with a pancreatic pseudocyst in a patient with an eating disorder.
