Pulmonary nocardiosis with multiple cavitary nodules in a HIV-negative immunocompromised patient

Abstract

The radiological manifestations of pulmonary nocardiosis are very diverse, and include non-segmental consolidation and pulmonary nodule(s). Cavitary nodules most commonly appear in AIDS patients, and are uncommon in non-AIDS patients. We report a case of pulmonary nocardiosis with bilateral multiple cavitary nodules in a HIV-negative 60-year-old man with nephrotic syndrome who was receiving corticosteroid treatment. It is suggested that pulmonary nocardiosis should be considered in the differential diagnosis of multiple cavitary nodules on chest radiographs, even in non-AIDS immunocompromised patients.
