Question: The patient is a 63-year-old white man referred for positive fecal occult blood on routine colon cancer screening. He was asymptomatic with a normal blood count. He had hypertension, gastroesophageal reflux disease, and coronary artery disease, all of which were stable on medical therapy. He had a splenectomy several years ago after a motor vehicle accident and a subsequent midline hernia repair. He had no prior history of pancreas, liver, or kidney diseases. Physical examination was unremarkable. Colonoscopy revealed a bulge in the cecum (left figure) and mildly inverted appendix. No other abnormalities were found. Abdominal CT scan was obtained (right figure). What is the diagnosis?
