Question: A 37-year-old woman was admitted owing to a pancreatic mass, which was incidentally found at chest computed tomography (CT) scan for the evaluation of pneumonia 3 months before admission. She was asymptomatic and her family history was unremarkable. She was not alcoholic and had no history of pancreatitis or abdominal surgery. A physical examination showed that the abdomen was soft and flat without tenderness on palpation. The initial routine laboratory test, including full blood count, urea, electrolytes, and liver function test, was within the normal limit.
