The Radiographic Appearance of Pulmonary Nocardiosis Associated with AIDS
1990
Pulmonary nocardiosis is a well-described infection in immunocompromised patients; however, it is less well documented in patients with AIDS. The pulmonary manifestation in 21 HIV-positive patients who developed pulmonary infection with Nocardia asteroides is described. The radiographic picture included lobar or multilobar consolidation (52 percent [11/21]), solitary masses (24 percent [5/21]), reticulonodular infiltrates (33 percent [7/21]), and pleural effusion (33 percent [7/21]). Cavitation was common (62 percent [13/21]), and upper lobes were more commonly involved (71 percent [15/21]). Although the radiographic picture is variable, nocardiosis should be suspected in an HIV-positive patient who has subacute pulmonary disease with an unexplained lung mass or cavitary lesions.
