Solitary caecal ulcer syndrome, a benign condition which mimics the CT appearance of caecal carcinoma

Solitary (or idiopathic) caecal ulcer syndrome is a rare entity whose initial clinical presentation usually suggests appendicitis. Imaging with barium enema or computed tomography (CT) may suggest caecal carcinoma. Definitive diagnosis is made at pathology. In this report we describe the clinical, radiological and pathological findings of a patient with solitary caecal ulcer syndrome, and illustrate the CT and pathological findings in a second patient.
