Abstract
Pseudocysts are usually due to preexisting pancreatitis which may be asymptomatic. Clinical features were abdominal pain and the presence of an intra-abdominal mass best revealed by serial x-rays of the upper gastrointestinal tract. Pulmonary pathology was prominently noted on chest films in 15 of 42 patients (35%), hydrothorax being a significant feature in 7 (17%). The glucose tolerance test or 2-hr. postprandial blood sugar determinations were the most important laboratory tests, a carbohydrate metabolic defect being manifest in 24 patients (57%). Serum diastase was elevated in only 17 (41%). Pseudocysts of the pancreas may bleed, rupture, provoke gastrointestinal hemorrhage, cause obstructive jaundice, or mimic neoplasm. They usually persist, but may spontaneously disappear.
