We reviewed radiographic and endoscopic features of gastrointestinal(GI)involvement in immunodeficiency diseases and graft-versus-host disease(GVHD). Although GI involvement of primary immunodeficiency with lymphocyte defect has been described to some extent, protozoal or parasitic infestations accompanied by malabsorption are major GI manifestations. In contrast, chronic colitis frequently occurs in primary leukocyte dysfunction such as chronic granulomatous disease and glycogen storage disease. The radiographic and endoscopic findings of chronic colitis mimic those found in inflammatory bowel diseases. Protozoal and parasitic infestations are also the major small intestinal involvement in HIV or HTLV-1 infection. In addition, fungal infection of the esophagus and GI ulcers induced by viral infection occur in cases of acquired immunodeficiency. In GVHD, heterogeneous gastrointestinal lesions are found anywhere within the GI tract. However, mucosal edema and sloughing are characteristic of the disease. There seems to be a need to interpret radiographic and endoscopic features of individual GI infections, because immuno-dysregulatory conditions are predisposed to the infection.
