title: Roentgenographic features of acute nonobstructive appendicitis: a case report.
abstract: We document a case of acute nonobstructive appendicitis and critically evaluate the pertinent literature. Although undoubtedly a rare entity, nonobstructive appendicitis may occur and should be differentiated from a normal appendix by barium enema examination. Mucosal and intramural inflammatory abnormalities are described which permit the diagnosis of nonobstructive appendicitis.
