Computed tomography findings in a case of hypogammaglobulinemia

A case of hypogammaglobulinemia in a 4.5-year-old boy is presented. The radiologist was the first physician to suggest this diagnosis by noting the absence of adenoidal and tonsillar lymphoid tissue on computed tomography in a patient with sinusitis. A review of the radiographic features of the primary immunodeficiency states is discussed.
