title: Spectrum of lymphoid hyperplasia: colonic manifestations of sarcoidosis, infectious mononucleosis, and Crohn's disease.
abstract: The radiographic pattern of nodular lymphoid hyperplasia, perhaps better called the lymphoid follicular pattern, has variously been described as an indication of disease and as a normal variant in the adult, with current opinion favoring the latter. We report 3 cases wherein this pattern resulted from definite pathologic processes: sarcoidosis, infectious mononucleosis, and Crohn's disease. Although usually of no pathological significance, the benign follicular pattern may reflect a variety of diseases.
