Villous hypertrophy of the small bowel in a patient with glucagonoma.
Mucosal thickening in the small bowel was seen on computed tomography (CT) in a patient with a pancreatic glucagonoma. A small bowel series demonstrated multiple fine filling defects throughout both jejunum and ileum associated with moderate fold thickening and prolonged transit time. Villous hypertrophy was indeed identified in a resected segment of jejunum. Elevated blood levels of enteroglucagon have previously been associated with small intestinal villous hypertrophy. Careful scrutiny of the bowel pattern on CT scans may suggest abnormalities which may then be confirmed by conventional barium studies. Such observations may change the evaluation of a clinical problem.
