Pulmonary Nocardiosis After Lung Transplantation

OBJECTIVE: The purpose of this study is to review reported radiographic clues to the diagnosis of pulmonary nocardiosis, as well as to describe and illustrate the high-resolution computed tomography findings of 7 patients with pulmonary nocardiosis after lung transplantation. CONCLUSIONS: Computed tomography findings of pulmonary nocardiosis after lung transplantation consist predominantly of nodules and cavitary lesions without any significant zonal or anatomic distribution. The diagnosis of pulmonary nocardiosis requires a high index of suspicion, as presenting symptoms are nonspecific, initial visualization is often not possible with routine stains, and identification requires prolonged cultures.
