title: Immunoglobulin deficiency diseases of the intestine.
abstract: Marshak has emphasized the role of the gastrointestinal tract as a major immunologic organ and described the radiologic findings of immunoglobulin deficiency diseases of the small intestine. According to his classification the radiologic findings include multiple nodular defects, edema and increased secretions associated with Giardiasis, a sprue-like pattern, and thickened folds. In this report, the role of the intestine in the immune response is briefly reviewed and several of the radiologic features of immune deficiency diseases and those of benign nodular lymphoid hyperplasia are illustrated.
