Rhodococcus equi (R. equi) has been reported as an occasional cause of pulmonary infection in severely immunocompromised hosts, including AIDS patients. Our purpose is to describe the radiologic findings in two AIDS patients with R. equi pneumonia. Chest radiographs showed right-upper-lobe consolidation and cavitation in both patients. Chest CT confirmed upper mediastinal involvement and precarinal lymphadenopathy in both cases. Multiple lung nodules related to the bronchi were also identified in one patient. In an AIDS patient from a rural area or with exposure to horses, the possibility of R. equi infection should be considered when cavitary pneumonia is present, even if there is mediastinal involvement and/or lymphadenopathy, or if multiple lung nodules are also present.
