title: The cecal diaphragm.
abstract: A detailed radiologic, colonoscopic, and histologic analysis is described in the case of a cecal web presenting as a "cecal mass." The demonstration of a transverse band-like lucency proximal to the ileocecal valve should prompt careful double-contrast barium studies, to which endoscopy may be added, enabling a correct diagnosis to be made.
