Curved plannar reconstruction with maximum intensity projection in lower gastrointestinal bleeding.

A 51-year-old man was admitted to the hospital with a history of hematochezia for the previous 16 hours. Abdominal computed tomography with contrast enhancement showed only slight punctate and linear high density in the ascending colon. Colonic curved plannar reconstruction with maximum intensity projection showed an accumulation of remarkable high-density material in the ascending colon. A colonoscopy revealed a polypoid eminence lesion with bleeding in the same location, 4 cm in the diameter. The patient underwent endoscopic mucosal resection and was discharged 2 days after surgery.
