Inside View: Pedunculated polyp of the ileum protruding from a large diverticulum

摘要

IntroductionA 52-year-old woman presented with iron deficiency anaemia and postprandial right lower quadrant pain. Abdominal examination was unremarkable and laboratory results showed mild anaemia (haemoglobin 11.3 g/dL). Upper and lower endoscopies did not reveal any source of bleeding. Video capsule endoscopy was performed which showed a large polypoid lesion in the mid-ileum (). Abdominal contrast enhanced CT demonstrated a heterogeneously enhancing pedunculated polyp measuring approximately 6 cm (). Retrograde double-balloon enteroscopy was performed which revealed a large pedunculated polyp with hyperplastic-like mucosa protruding from a large diverticulum located approximately 70 cm proximal to the ileocaecal valve (). The stalk appeared to arise from the base of the diverticulum (). A technetium-99m pertechnetate scintigraphy revealed no ectopic gastric mucosa.Video capsule endoscopy shows a large polypoid lesion.
