Usefulness of virtual colonoscopy in the diagnosis of symptomatic large colonic lipomas

SUMMARY Lipomas of the colon are uncommon tumour of the gastrointestinal tract, but cause diagnostic difficulty when they are symptomatic. We reported two cases of symptomatic, large colonic lipoma. Colonoscopy was incomplete because of the narrowing lumen caused by lipomas. By the help of computed tomography colonography/virtual colonoscopy, colonic lipomas were diagnosed correctly, but also proximal colon was examined.
