title: Pulmonary infections in the immunocompromised host.
abstract: The lung is an organ that is particularly susceptible to infection in the immunocompromised host. Patterns of involvement produced on the chest radiograph include (1) lobar or segmental consolidation; (2) nodules with rapid growth and/or cavitation; and (3) diffuse lung disease. There is a general correlation between the type of radiographic pattern and the microorganism producing the pneumonia. Invasive diagnostic procedures include needle aspiration, transbronchial, and open lung biopsy.
